Final Pressure of a Gas After Heating

A system consists of a gas enclosed in a sealed container. The gas initially occupies a volume of 2.0 liters at a temperature of 300 K and has a pressure of 1.0 atm. The container is then heated, causing the temperature to rise to 600 K while maintaining the volume constant.

According to the principles of thermodynamics, what is the final pressure of the gas in the container after heating?
