College Chemistry Instructor Guide

(PS-3803A)

College Instructor edition with 36 experiments covering introductory and general chemistry topics.

Molar Volume of a Gas

Lab Summary

Use an absolute pressure sensor and stainless steel temperature sensor to determine the molar volume of a gas by relating pressure, volume, and temperature.

Theory

Students determine the molar volume of a gas by relating pressure, volume, and temperature.

Method

Students gain experience conducting the following procedures:

  • Conducting an experiment in a closed container that generates hydrogen gas while maintaining constant temperature and monitoring pressure.
  • Calculating the molar volume of the generated gas and converting that to standard temperature and pressure conditions.

Sensors / Equipment Used:
