  1. Convert degrees C to degrees K.
    K = C + 273
    Convert torrs to atm.
    atm = torrs / 760

    Substitute in PV = nRT and solve for V

  4. Must think of this as a ratio. The conditions are all the same. If 3.21mol occupies 56.2L then 5.29mol occupies X liters.

    3.21mol/56.2L=5.29mol/X

    Cross multiply and divide.

    Ans= 92.6L

  7. v1/n1 = v2/n2
    56.2 / 3.21 = v2 / 5.29
    v2= 92.6L
