Question

What amount of heat is exchanged when 106.2 grams of substance Y goes from a liquid at 35 degrees Celsius to a solid at the same temperature?
Melting point of substance Y = 35 degrees C; ∆Hvaporization = 3.67 J/mol; ∆Hfusion = 3.30 J/mol. MWsubstance y = 28.22 g/mol.

-12.4 J
-3.51 x 10^2 J
1.24 x 10^1 J
351 J
