i am not understanding how to solve this how many moles of gas are present in a sample that is at 756 mm Hg pressure, has a volume of 5.3 L, and a temperature of 38 degrees C?

  • Chemistry -

    PV=nRT

    756mmHG= 0.994atm
    38C=311K

    (0.994atm)(5.4L)=n(0.08206 L/atm/mol/k)(311K)

    n= 0.21 mol

    thank you
