Lesson: Molar Gas Volume Chemistry

In this lesson, we will learn how to use molar gas volume, under standard conditions, to calculate the volume and number of moles of a gas.

Lesson Plan

Students will be able to

state Avogadro’s law relating gas volume to the number of moles,
state the formula for calculating molar gas volumes,
recall the standard molar gas volume at standard temperature and pressure (STP) to be 22.4 liters per mole,
describe the conditions that constitute STP (1 atm, ),
calculate the volume or number of moles of a gas at STP.

Q1:

What is the equation relating the volume of a gas, , to the number of moles of the gas, , and its molar volume, ?

Q2:

Which of the following statements best describes molar volume?

Q3:

Which of the following is the correct definition of the standard molar gas volume?
