A sample of an ideal gas has a volume of 0.500 L at 25 degrees celcius and 1.20 atm pressure. What is its volume at 75 degrees celcius and 3.60 atm?

The ideal gas law is PV = nRT.

First you need to manipulate the equation to splice for volume,

Which will be V = nRT/P

Now you need to input the numbers for each variable. Make sure to remember what the value R equals and it's units. R = 0.08206 L•atm/n•K
