You have 4 hydrogens in one NH4 compound, and you have 3 NH4, so that gives you 12 H and 3 N.
You also have a coefficient of 2 in front of (NH4)3, so that means you would multiply 12 H atoms by 2 and 3 N by 2, giving you 24 hydrogen atoms and 6 nitrogen atoms.
You also have 1 Phosphorus atom, and 4 oxygen atoms, so now add all your individual atoms up:
24 hydrogen + 6 Nitrogen + 1 Phosphorus + 4 Oxygen = 35 atoms in total

The best data for comparing the electrostatic forces between the molecules of different substances can be obtained through this procedure: B. Heat each substance in liquid form to its boiling point. Measure the temperature of each substance.
An electrostatic force can be defined as a force of attraction or repulsion between two (2) stationary and electrically charged particles of a substance.
Basically, the force between two (2) charges is inversely proportional to the square of the distance between them and directly proportional to the magnitude of their charges.
In the molecule of a substance, an electrostatic force is mainly responsible for holding its atoms together while giving the molecule both structure and strength.
During an experiment that is aimed at obtaining the best data to compare the electrostatic forces between the molecules of different substances, the procedure that should be adopted include:
Each of the substance should be heated in liquid form to its boiling point.The boiling temperature of each substance should be measured and recorded.From the data, a comparison should be done to know which molecule contain atoms that are tightly held together.Read more: https://brainly.com/question/24031197

the enthalpy of combustion of gasoline is about 45 kj/g. the amount of energy needed to heat 1 g of water from 20 °c to 100 °c is 80 °c x 4.18/g•°c. the enthalpy of vaporization of water is 2540 j/g. what mass of water at 20 °c can 1 g of gasoline heat and boil?
Answers
The mass of water that can be boiled by 1 g of gasoline by raising its temperature from 20 °c to 100 °c is 17.6 g.
Now, we know that energy can not be created nor destroyed but it can be converted from one form to another.
The heat produced by the gasoline is equal to the heat gained by water. Mathematically;
1g × 45 × 10^3 = [1 g × 4.18 × (100 - 20) + 2540m]
45 × 10^3 = 334.4 + 2540m
45 × 10^3 - 334.4 = 2540m
m = 45 × 10^3 - 334.4 /2540
m = 17.6 g
The mass of water that can be boiled by 1 g of gasoline by raising its temperature from 20 °c to 100 °c is 17.6 g.

A chemist makes a solution of zinc acetate by dissolving 20.5 g Zn(C₂H₃O₂)₂ in 105 mL H₂O. What is the concentration of this zinc acetate solution?
Answers
The concentration of the zinc acetate, Zn(C₂H₃O₂) solution is 1.067 M
We'll begin by calculating the number of mole in 20.5 g of Zn(C₂H₃O₂)₂Mass of Zn(C₂H₃O₂)₂ = 20.5 g
Molar mass of Zn(C₂H₃O₂)₂ = 65 + 2[(12×2) + (3×1) + (16×2)]
= 65 + 2[59]
= 183 g/mol
Mole of Zn(C₂H₃O₂)₂ =?Mole = mass / molar mass
Mole of Zn(C₂H₃O₂)₂ = 20.5 / 183
Mole of Zn(C₂H₃O₂)₂ = 0.112 mole Finally, we shall determine concentration of Zn(C₂H₃O₂). This can be obtained as follow:Mole of Zn(C₂H₃O₂)₂ = 0.112 mole
Volume = 105 mL = 105 / 1000 = 0.105 L
Concentration of Zn(C₂H₃O₂)₂ =?Concentration = mole / Volume
Concentration of Zn(C₂H₃O₂)₂ = 0.112 / 0.105
Concentration of Zn(C₂H₃O₂)₂ = 1.067 MTherefore, the concentration of the zinc acetate, Zn(C₂H₃O₂) solution is 1.067 M

Hope this helps! :^)
94. 125 moles are present in 5.67x10^25 atoms of Carbon (C).
What is mole?
The mole is a unit of measurement that is comparable to well-known units like pair, dozen, bulk, etc. It offers a precise count of atoms or molecules in a large sample of materials.
The amount of substance that has the same number of discrete entities (atoms, molecules, ions, etc.) as the number of atoms in a sample of pure 12C weighing exactly 12 g is known as a mole.
The word "mole" has a "big mass" or "bulk" sense in Latin, which is congruent with its use as the name for this unit. The mole establishes a connection between bulk mass, which is a simple macroscopic attribute to measure, and the number of atoms, molecules, and other fundamental units, which is a crucial fundamental property.
Therefore, 94. 125 moles are present in 5.67x10^25 atoms of Carbon
(C).
