I need help in using gas laws to solve problems.

I need help with this question:

What is the pressure in atmospheres exerted by a 0.500 mol sample of oxygen gas in a 10.0 L container at 298 K?

Also what formula would I use to solve the pressure in this problem?

Also in order to get the answer from the above question you would need to round the answer that you would get to the hundredths place.

PV = nRT.

P in atmospheres, V in liters, n is number of mols, R is gas constant of 0.08206 L*atm/mol*K and T is temperature in Kelvin. You will need to follow whatever instructions your teacher has given.
