**Question 1**

What statement best describe the relationship between the terms chromosomes, genes and nuclei

Question 2

Which of these statements best describes the relationship between the molar mass and density of a gas?

a) The smaller the molar mass, the larger the density.

b) The larger the molar mass, the larger the density.

c) The larger the molar mass, the smaller the density.

The problem wants to establish the relationship between the molar mass of a gas sample to its corresponding density. In order to establish the relationship between the molar mass and density of a gas, we will use the Ideal Gas Law equation. The equation involves the number of moles and volume of a gas sample. This will help to establish the equation that relates the molar mass and density.

Question 3

A 2.10-L vessel contains 4.65 g of a gas at 1.00 atm and 27.0 degrees Celsius.

a. Calculate the density of the gas in grams per liter.

b. What is the molar mass of the gas?

The ideal gas equation is used to find the any missing term of any gas such as molar mass, mass, pressure, volume, temperature of a gas. The ideal gas equation is based on the ideal gas law.

Answer to question 1

Answer to question 2

The equation for the Ideal Gas Law is:

We will express the number of moles in terms of mass and molar mass.

We know that density is equal to mass over volume (mass/volume). We can derive an equation for density.
