Problem Statement:
How many mol of CH4 are in a 150 L tank exerting a pressure of 20.0 atm when the temperature is 24.0 degrees Celsius?

 

Express each variable in terms of the unit that corresponds to the units in R.

R has units of L atm mol-1 K-1 Pressure has units of atm, Volume has units of Liters, and Temperature has units of Kelvins. Pressure and volume are already in their proper units. Tmperature must be converted from degrees Celsius to Kelvins. The equation to do that is;

K = 273.15 + degs Celsius

K = 273.15 + 24.0

K = 297
