How much heat is needed to increase the temperature of 60 g of H2O from ice at -5C to liquid at 20C?

• Chemistry -

q1 = heat to move T of ice at 5C to ice at zero C.
q1 = mass ice x specific heat ice3 x (Tfinal-Tinitial)

q2 = heat to melt the 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 20 C.
q3 = mass H2O x specific heat H2O x (Tfinal-Tinitial)

Qtotal = q1 + q2 + q3.
