5. When an excess of Zn(s) is added to 125 mL of 0.150 M CuSO4(aq) in a constant-
pressure calorimeter of negligible heat capacity, the temperature of the solution rises
from 21.20°C to 28.97°C. Assuming the density and specific heat of the solution are the
same as for pure water (1.00 g/mL and 4.184 J/g °C), determine the molar enthalpy
change of the following reaction. Ignore the specific heats of the metals.
Zn(s) + CuSO4(aq) → ZnSO4(aq) + Cu(s)
a. -4.06 kJ/mol
6-217 kJ/mol
c. -27.1 kJ/mol
d. -610. kJ/mol
e. -3390 kJ/mol
