The gaseous product of a reaction is collected in a 25.0-L container at 27 C. The pressure in the container is 216 kPa, and the gas has a mass of 96.0g. What is the molar mass of the gas?

Use PV = nRT and solve for n. Remember T must be in Kelvin.
Tnen n = grams/molar mass. Solve for molar mass. Be careful with units for R and P. I would convert kPa to atmospheres and use 0.08206 for R.
