If a large office building is 1.07 x 10^2 meters long, 31 meters wide. and 4.25 x 10^2 meters high, then the volume of the building would be 1409725 meters cube.
What is density?It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.
As given in the problem we have to calculate the volume of a large office building having the dimensions of 1.07 x 10 ^2 meters long, 31 meters wide, and 4.25 x 10^2 meters high.
The volume of the office building = length × width × height
=107 × 31 × 425
=140925 meters cube
Thus, the volume of the building would be 140925 meters cube.

Density is a physical property of a molecule that’s measured as mass per unit volume. (a) Given that density is usually expressed in the units of g/cm^3, calculate the density of a cube of plastic that has a mass of 2.331 g and an edge length of 1.500 cm (volume of a cube is V = l^3). (Show work pls + WILL MARK BRAINLIEST)
Answer:
0.690666... g/cm^3
Explanation:
density=mass/volume. mass is 2.331 g and using the length we can determine that the volume of the cube is 3.375 cm^3. 2.331/3.375= 0.6906666....

The answer is 0.81 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass of metal = 10.5 g
volume = 13 cm³
We have
[tex]density = \frac{10.5}{13} \\ = 0.8076923...[/tex]
We have the final answer as
0.81 g/cm³Hope this helps you
Answer:
0.807
Explanation:
mass/volume = density
10.5/13 = 0.807

67 kg = 6.7×10⁷ mg.
Explanation:
The following data were obtained from the question:
Mass in Kg = 67 kg
Mass in mg =.?
Thus, we can obtain the mass in milligrams (mg) as follow:
1 kg = 1×10⁶ mg
Therefore,
67 kg = 67 kg × 1×10⁶ mg / 1 kg
67 kg = 6.7×10⁷ mg
Therefore, 67 kg is equivalent to 6.7×10⁷ mg

What is the molecular geometry of PBr3? A. trigonal pyramidal B. trigonal planar C. linear D....
The geometry of PBr₃ is trigonal pyramidal. Therefore, option A is correct.
Trigonal pyramidal geometry refers to the molecular geometry around a central atom in a molecule or ion where there are three bonded atoms and one lone pair of electrons. This geometry is commonly found in molecules with a central atom surrounded by three bonding pairs and one non-bonding pair of electrons.
The term "trigonal" refers to the arrangement of the three bonding pairs, which are positioned in a flat, triangular shape around the central atom. The term "pyramidal" indicates that the lone pair of electrons occupies the fourth position, giving the molecule a three-dimensional pyramid-like shape.

When does the shape of a molecule affect its polarity?
A. When the molecule contains ionic bonds
B. When the molecule contains polar bonds
C. When the molecule contains hydrogen bonds
D. When the molecule contains nonpolar bonds
Answer:
B When the molecule contains polar bonds.
Explanation:
AP-EXpert
The shape of a molecule affect its polarity, when the molecule contains polar bonds because polarity depends on polar bonds.
What is the effect on polarity?The polarization of a molecule greatly depends on the shape of the molecule. The net dipole moment occurs only due to the uneven distribution of electrons between the two atoms.
So we can conclude that the shape of a molecule affect its polarity, when the molecule contains polar bonds because polarity depends on polar bonds.

Using dimensional analysis How many mg are there in 8.75 X 107 kilograms?
Conversion factors:
[1000 g = 1 Kg]
[1000 mg = 1 g]
Can you please show the work
Answer:
8.75×10¹³ mg
Explanation:
From the question given above, we obtained:
Mass (in Kg) = 8.75×10⁷ Kg
Mass (in mg) =?
Next, we shall convert 8.75×10⁷ Kg to grams (g). This can be obtained as follow:
1 Kg = 1000 g
Therefore,
8.75×10⁷ Kg = 8.75×10⁷ Kg × 1000 g/1 kg
8.75×10⁷ Kg = 8.75×10¹⁰ g
Therefore, 8.75×10⁷ Kg is equivalent to 8.75×10¹⁰ g.
Finally, we shall convert 8.75×10¹⁰ g to mg. This can be obtained as illustrated below:
1 g = 1000 mg
Therefore,
8.75×10¹⁰ g = 8.75×10¹⁰ g × 1000 mg/ 1 g
8.75×10¹⁰ g = 8.75×10¹³ mg
Thus, 8.75×10⁷ Kg is equivalent to 8.75×10¹³ mg.

Answer:
[Rn]7s25f14
Explanation:
[tex][Rn]5f^{14}7s^2[/tex] is the electron configuration for nobelium (No).
Explanation:
The electronic configuration of an element is the distribution of its electrons in different energy levels around the atomic nucleus.It is written with help of an atomic number of an element.Given:
The element nobelium.
To find:
The electronic configuration of nobelium
Solution:
The atomic number of nobelium is 102.
The number of protons = Atomic number = 102
The number of electrons = Number of protons = 102
There are 102 electrons in atom nobelium and they will be filled according to the Aufbau rule that the electron will be filled in a subshell with lower orbital energy.
The electronic configuration of nobelium :
[tex][No]=1s^22s^22p^63s^23p^63d^{10}4s^24p^64d^{10}5s^25p^64f^{14}5d^{10}6s^26p^65f^{14}7s^2[/tex]

Is neon transparent translucent or opaque
Neon is transparent opaque as it is light, colorless and order less inert noble gas.
What are noble gas?Noble gas are defined as the element that belong to group 18 of the modern periodic table.
It is also known as inert gas or aerogene.
Noble gas are light, transparent, colorless and order less gases.
They are the group of six inert or non reactive gases.
Noble gases are odorless, colorless, nonflammable gases with negligible chemical reactivity.
Noble gases are exceedingly stable and unlikely to form chemical bonds due to their complete valence electron shells, which have no tendency to add or lose electrons.
Noble gas were originally classified as group 0 in the periodic table because it was thought they had a valence of zero, which means their atoms could not mix with those of other elements to form compounds.
Thus, Neon is transparent opaque as it is light, colorless and order less inert noble gas.

Calculate the volume of a liquid with a density of 5.35 g/mL and a mass of 62.0 g.
Answer to the proper significant figures and include the proper unit.
My answer was 11.6 mL, but it was wrong.
Answer:
V= 12mL
Explanation:
you had the right idea with your Significant figures however, when we divide we see that it requires 2 significant figures as our least amount. this is because when looking at our division, 62 has 2 sig. fig. while 5.35 has a total 3. when looking at your answer we see that you had a total of 3 sig. figures. so in actuakity you had to round up to 12 and not to the tenths because the decimal makes .6 count as your third sig fig.
