PV=nRT

find n, given mass. Then find temp. Watch units of R and your other units to make certain they are in the same units.
Use PV = nRT
thanks.. tried this formula several times, must be putting numbers in the wrong place..if R equals 0.0821L x atm per mole x K..and I don't know what the temp is?
