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?
Problem Solving Strategy:
Since this is a problem about a gas, and all the data
provided are physical properties we conclude it is an Ideal Gas Law Problem
and we need to construct a table to associate values in the problem statement
with the variables in the Ideal Gas Law (PV = nRT).
So the table would now look like;
|
P
|
V
|
n
