35g of water at 55 degrees Celsius is heated until it is all steam at 100 degrees Celsius. How much every was added?

• chemistry -

q1 = heat to move H2O from 55 to 100 C.
q1 = mass x specific heat liqud water x (Tfinal-Tinial). Tfinal = 100; Tinitial = 55.

q2 = heat to vaporize liquid water to steam @ 100 C.
q2 = mass water x heat vaporization.

total q = q1 + q2.
