asked • 11/29/15# Ideal gas law problem?? - CHEMISTRY

What is the temperature of methane gas (CH4) if 4.78 mol of gas are collected in 9.2 L at 789 torr?

PV=nRT

All help is greatly appreciated!!

Here is what I was thinking.. but I am not sure if it is correct.

T = PV / nR

T =(789 torr)(9.2 L) / (4.78 mol)(0.0821 Latm / mol*K) = 18496.679 = 18000 K...

That answer seems really big to me.. thank you for the help in advance

Convert torr into atm. 789 torr / 760

Pressure has to be in atm for the ideal gas law equation to work.
