How many calories does it take to convert 22 grams of liquid water with a temperature of 48 degrees C to steam?

  • chemistry -

    q1 to move T water from 48 to 100.
    q1 = mass water x specific heat water x (Tfinal-Tinitial).

    q2 to vaporize the water.
    q2 = mass water x delta Hvaporization.

    Total = q1 + q2.
