A gas cylinder containing 6.38 mol of neon has a pressure of 491 mm Hg at 295 K. If 3.22 mol of helium is added to this cylinder, at constant temperature and volume, what will be the pressure in the cylinder?

  • Chemistry 140A - ,

    PV=nRt

    at constant volume and temp


    P1/P2=n1/N2

    P1=491mmHg*(6.38+3.22)/6.38
