How much energy (in kcal) is needed to convert 53.2 g of water at 55.0 C to steam at 100.0 C

  • Chemistry -

    q1 = energy to raise T from 55C to 100 C.
    q1 = mass x specific heat x (Tfinal-Tinitial).

    q2 = energy to vaporize all of the water.
    q2 = mass x deltaHvap.

    total heat = q1 + q2
