How many grams of sugar must be dissolved in 150 mL of water to make a solution with a concentration of 0.6 g/mL?

Answers

Answer 1

Answer:

250

Explanation:

all you have to do is divide them its simple division cause its by the volume by the density

Answer 2

Mass can be calculated by using moles which can be further calculated from multiplication of Molarity to volume. The mass of sugar to make this solution is  8.6 kg.

What is molarity?

Molarity can be calculated by dividing  number of moles of solute by volume of solution in litre. Molarity is affected by temperature. Its unit is mole/litre. It measure the concentration of any solute in a solution.

Other concentration terms are molality, normality and mole fraction. Molarity can be used to find out the ionic strength of any solution

Mathematically,

Molarity= number of moles of solute/volume of solution in litre

Where,

moles= given weight /by molecular weight

         = w/ 96.0858

Substituting values in equation 1

0.6=(w/96.0858)/(150 )

w=8.6 kg

Thus the mass of sugar is 8.6 kg.

If an atom has 56 protons and 58 neutrons, how many electrons
would this atom have?

Answers

Because the protons = the electrons so the atom will have 56 electrons.

This atom would have 56 electrons.

Atomic Structure:

In a neutral atom, the number of protons and number of electrons are same which is equal to the atomic number of an atom.The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

So, it is given that;

Number of protons=56

Number of neutrons=58

Thus, number of electrons=56 (since, the number of protons and number of electrons are same)

Based on the three formulas shown, use one of them to solve for the purple yellow and red box and explain how you did it.

Answers

P = 11.133 atm (purple)

T = -236.733 °C(yellow)

n = 0.174 mol(red)

Further explanation  

Some of the laws regarding gas, can apply to ideal gas (volume expansion does not occur when the gas is heated),:  

Boyle's law at constant T, P = 1 / V  Charles's law, at constant P, V = T  Avogadro's law, at constant P and T, V = n  

So that the three laws can be combined into a single gas equation, the ideal gas equation  

In general, the gas equation can be written  

[tex]\large {\boxed {\bold {PV = nRT}}}[/tex]

where  

P = pressure, atm  

V = volume, liter  

n = number of moles  

R = gas constant = 0.08206 L.atm / mol K  

T = temperature, Kelvin  

To choose the formula used, we refer to the data provided

Because the data provided are temperature, pressure, volume and moles, than we use the formula PV = nRT

Purple box

T= 10 +273.15 = 373.15 K

V=5.5 L

n=2 mol

[tex]\tt P=\dfrac{nRT}{V}\\\\P=\dfrac{2\times 0.08205\times 373.15}{5.5}\\\\P=11.133~atm[/tex]

Yellow box

V=8.3 L

P=1.8 atm

n=5 mol

[tex]\tt T=\dfrac{PV}{nR}\\\\T=\dfrac{1.8\times 8.3}{5\times 0.08205}\\\\T=36.42~K=-236.733^oC[/tex]

Red box

T = 12 + 273.15 = 285.15 K

V=3.4 L

P=1.2 atm

[tex]\tt n=\dfrac{PV}{RT}\\\\n=\dfrac{1.2\times 3.4}{0.08205\times 285.15}\\\\n=0.174~mol[/tex]

Gold atoms can be identified based on the number of which subatomic particles?
A.neutrons
B.electrons
C.nuclei
D.protons

Answers

Answer:

D.protons

Explanation:

Gold is a chemical element and it is the element 79 on the periodic table. Thus, it has an atomic number of 79. The chemical symbol for Gold is Au, it is chemically classified as a transition metal and as a solid at room temperature.

Generally, the chemical element Gold is known to be malleable, ductile and a good conductor of electricity and heat. Also, it is a non-toxic chemical element with a beautiful lustrous sheen.

Gold atoms can be identified based on the number of protons (79) because it represent its atomic number, which is what is used to differentiate an atom of an element from the atom of another chemical element.

When a candle burns it produced 41,300 Joules per 1 gram. Use dimensional analysis to convert this to Calories per pound.

1 cal = 4.184 J

16 ounces = 1 pound

1 ounce = 23.5 grams

1 Calorie= 1000 calories

Answers

Answer:

4477381.7 calories/pound

Explanation:

It is given that,

When a candle burns it produced 41,300 Joules per 1 gram.

We need to convert it into calories per pound.

We know that,

1 cal = 4.184 J

⇒ 1 J = (1/4.184) cal

1 pound = 453.592 grams

⇒1 g = (1/453.592) pounds

Now,

[tex]41300\ \text{Joules per gram}=\dfrac{41300\ \text{Joules}}{\text{gram}}\\\\=41300\times \dfrac{\dfrac{1}{4.184}\ \text{calories}}{\dfrac{1}{453.592}\ \text{gram}}\\\\=4477381.7\ \text{calories/pound}[/tex]

Hence, 41,300 Joules/gram = 4477381.7 calories/pound.

The following data was collected: 5.5 m; 5.3 m; 5.4 m. The actual length is 5.4 m. What is the accuracy and precision for this set of measurements?

Answers

Answer:

The measurement is precise and accurate

Explanation:

The accuracy of a measurement of length is often indicated by how "precisely" the length measurement can be read depending on the type of measuring instrument used scale.

Looking at the measurement, we can see that the values lie between ±0.1 from the expected values hence it is accurate.

Also, the values differ from each other by ±0.1 hence it the measurements are precise.

Answer:

Accuracy:

5.5 = 98.15%

5.3 = 98.15%

5.4 = 100 %

Precision:

5.5 ± 0.14

5.3 ± 0.14

5.4 ± 0.14

Explanation:

Accuracy is determined using; 100% - % error

% error = absolute error/actual value * 100%

5.5 - 5.4/5.4 * 100% = 1.85%

accuracy = 100 % - 1.85 % = 98.15%

5.3 - 5.4/5.4 * 100 5 = 1.85%

accuracy = 100 % - 1.85 % = 98.15%

5.4 - 5.4/5.4 * 100  % = 0 %

accuracy = 100 % - 0% = 100%

Precision is determined by obtaining the standard deviation of the mean;

s = √{∑(|x - m|)²/(n - 1)}

where x is the value, m is mean of values , n is number of values

mean = (5.5 + 5.3 + 5.4) / 3 = 5.4

deviations from mean, (x - m) are as follows;

|5.5 - 5.4| = 0.1

|5.3 - 5.4| = 0.1

|5.4 - 5.4| = 0

∑(x - m)² = (0.1 + 0.1 + 0) ²= (0.2)² = 0.04

(n - 1) = 3 - 1 = 2

s = √(0.04/2)

s = ± 0.14

Therefore, the precision of each measurement is as follows;

5.5 ± 0.14

5.3 ± 0.14

5.4 ± 0.14

Which of the following types of soil has the greatest permeability?

A. Loam

B. Sandy

C. Clay

D. Silty

Answers

Answer:

Sandy soil

Explanation:

Sandy soil has the greatest permeability of all soil types. It has a high amount of pore space and grain size.

Permeability is the ability of fluids to pass between the grains of a substance, here soil. It is usually a function of the size of the pore spaces and the grain size.

Sandy soils are usually made up of particles with sand-sized shapes and dimension. They have bigger and finer grains with little to no cement. This allows for a high level of permeability with no impediment to flow.Clay soil has very fine grain and with very low permeability. Silty soils have fair enough permeability and the permeability of loam straddles between that of sand and clay.

Permeability is very important for determining the quality of soils.
