Use PV=nRT
You are missing the Temperature in Kelvins and the gas constant (R).

You need to become comfortable with using the ideal gas law:
PV=nRT where P is the pressure in the container, V is the volume, n is the number of moles of the gas, T is the temperature in Kelvin, and R is the gas constant.
The value of R depends on the units used for pressure and volume. The most common value of R is 0.0821 L atm/mol K. I'm sure you can find a value of R using kP for pressure, OR you can convert the pressure from kPa to atm.
Gas law problems are really quite simple, and as in your later questions, you will have to use stoichiometry and then combine that with the ideal gas law equation.
