A 3.80 L cylinder contains 6.83g of methane, CH4, at a pressure of 3320 mmHg. What is the temperature of the gas?
I know you use the formula PV= nRT, but I can't seem to get two sides equal each other, thus having the wrong temp. My guess is that I have to change mmHg to a different unit.
If you are using P in anything other than atm, that's not right. 3320/760 = atm.
V must be in L and T will be in kelvin.
