    Answer:

      2 Atm; 2.016 g

    Explanation:

    Changing the volume without changing the temperature or mass only changes the pressure. Volume and pressure are inversely proportional so halving the volume will double the pressure.

    P = 1 Atm, T = 0 °C are “standard” temperature and pressure (STP). The volume of 1 mole of gas is 22.4 L under these conditions. That means the amount of hydrogen gas in the cylinder is 1 mole, so has a mass of 2.016 g.

    After the volume reduction, the pressure is 2 Atm, and the mass remains 2.016 g.
