Question

Consider the specific heats H2O(s) = 2.09 J/g ·◦C, H2O (l) = 4.18 J/g ·◦C, and H2O(g) = 2.03 J/g ·◦C.
The heat of fusion for water is 334 J/g and its heat of vaporization is 2260 J/g. Calculate the amount of heat required to convert 91 g of ice at −36◦C completely to liquid water at 60◦C.
Answer in units of kJ.
q for ice at -36 C to zero C is
q = mass ice x specific heat ice x (Tfinal-Tinitial) = q1

q for water at zero C to water at 60 C= q2
q2 = mass water x specific heat water x (Tfinal-Tinitial)

qtotal = q1 + q2 = ?
