the heat of fusion water is335 J/g. The heat of evaporization of water is 2.26 kJ/g, the specific heat of ice is 2.05 J/Deg/g, the specific heat of steam is 2.08 J/deg/g and the specific heat of liquid water is 4.184 J/deg/g. How much heat would be needed to convert 12.09 g of ice at 17 degree C to steam at 135 C

Work this problem in pieces.
q with a single phase (liquid to liquid, vapor to vapor, solid to solid) = mass x specific heat in that phase x (TfinalTinitial).
q at a phase change is
mass x heat fusion at zero C.
mass x heat vaporization at 100 C.
Then add each segment of q to find total Q.
