1. What volume will a mixture of 5.00 mol of H2 and 0.500 mol of CO2 occupy at STP?

  • Chem 22 -

    Use PV = nRT. Substitute 5.5 for n.

    Here's my work please tell me if its right DrBob222;
    P=760 torr or 1 atm
    V=?
    T= 273 K
    n= 5.00 + 0.500= 5.5 mole

    V= nRT/P
    = (5.5 mol)(0.0821 L x atm/mol*K)(273 K)
    divided by 1 atm
    = 123.27 L
