Problem

How much energy is required to heat 36.0 g H 2O from a liquid at 65°C to a gas at 115°C?  The following physical data may be useful.

ΔHvap = 40.7 kJ/mol

Cliq = 4.18 J/g°C

Cgas = 2.01 J/g°C

Csol = 2.09 J/g°C

Tmelting = 0°C

Tboiling = 100°C

A) 52.7 kJ      B) 91.7 kJ      C) 87.7 kJ      D) 63.5 kJ      E) 10.9 kJ
