Ideal Gas Law

Example Problem

1) The ideal gas law is an approximation of how gases will behave under certain conditions. The state of an amount of gas is determined by its pressure, volume, and temperature. This law then contains an equation of the state of a hypothetical ideal gas.

Step 1: Do Conversions: n= must be converted to moles T= must be converted to Kelvin

P= Pressure- must be in Atmospheres.V= Volume- must be in Liters.n= Moles- must be in moles. R= Ideal Gas Constant= .0821T= Temperature- must be in K

How To Solve

Temperature= 0 C= 273KPressure= 1 atm= 760 torr= 760 mmHg

What volume would a 5.50 g sample of oxygen gas at a pressure of 1.50 atm and a temperature of 23.0 OC occupy?

Step 2: Plug in and Solve:
