Lesson: Particle Model of an Ideal Gas High School Physics

Physics

In this lesson, we will learn how to calculate the relationship between the number of particles or moles in an ideal gas and the values of its bulk properties.

Worksheet

Q1:

Find the number of moles of carbon atoms that is equal to atoms. Use a value of 12.0107 g/mol for the molar mass of carbon and use for the value of Avogadro’s number. Answer to three significant figures.

Q2:

A gas at a pressure of 125 kPa and a temperature of 485 K consists of particles with a molar mass of 30.5 g/mol. Find the density of the gas. Use 8.31 m²⋅kg/s²⋅K⋅mol for the value of the molar gas constant. Answer in kilograms per cubic meter to three significant figures.

Q3:

Find the number of lithium atoms that is equal to 7.25 moles of lithium atoms. Use a value of 6.941 g/mol for the molar mass of lithium and for the value of Avogadro’s number. Answer to three significant figures.
