a 1.00g sample of water is allowed to vaporize completely in a 10.0L container. What is the pressure of the water vapor at 150 degrees celsius?

  • chemistry -

    Use PV = nRT.
    n = 1.00g/molar mass H2O
    Don't forget T must be in kelvin.

  • chemistry -

    PV=nRT
    P=?
    V=10L
    n=0.056mol
    R=0.082 atm*l/mol*K
    T=423K

    P=nRT/V
    P=(0.056mol)(0.082atm*l/mol*K)(423K)/(10L)
    P=0.1942 atm
