What is the temperature of 16.45 moles of methane gas in a 4.95 L container at 4.68 atm?

You have to use the ideal gas law of PV=nRT.

In this case, you just have to plug in the given variables.

P (pressure) = 4.68 atm

V (volume) = 4.95 L

n (number of moles) = 16.45

R (gas constant) =.0821

T (temperature) is what youre trying to solve so:

(4.68) * (4.95) = (16.45) * (.0821) * T

To get T by itself, divide both sides by (16.45) * (0.821) to get T of 17.15.
