According to the ideal gas law, PV=nRT, pressure (P), volume (V), and temperature (T) are directly proportional to the number of moles of gas (n). As the number of moles of gas is doubled at constant temperature and volume, both P and V would double to maintain the equality of the equation. So, the pressure of the gas would also double.
