Determination of Ideal Gas Law Constant Student Name: Allyson May Date: 10/28/20
Introduction The purpose of this lab is to use the ideal gas law to determine the relationship of pressure, volume, and number of moles. In this lab, oxygen gas will be collected from the hydrogen peroxide reaction to find the ideal gas constant.
