q1 = heat to move solid ice from 50 C to zero C.
q1 = mass ice x specific heat ice x (TfinalTinitial).
q2 = heat to melt ice at zero C to liquid water at zero C.
q2 = mass ice x heat fusion.
q3 = heat to move liquid water from zero C to 100 C
q3 = mass water x specific heat water x (TfinalTinitial)
q4 = heat to convert liquid water at 100 C to vapor at 100 C.
q4 = mass water x heat vap.
qTotal = q1 + q2 + q3 + q4
