Question 190428
The volume of gas at a constant temperature varies inversely as the pressure. Find the volume of a gas under pressure of 24 pound per cubic centimeter if the gas occupies a volume of 123 cubic centimeters under a pressure of 20 pounds per cubic centimeter. 
I know i need to use the formula
Q=k/m but I am not quite sure what goes where.
-------------------------------------
Volume = k/pressure
---
1st: solve for "k":
123 = k/20
k = 2460
------------
So the equation is Vol = 2460/pressure
------------------------------------------
Find the volume of a gas under pressure of 24 pound per cubic centimeter 
Vol = 2460/24
Volume = 102.5 cc
