Question
0.700 moles of an unknown
solid is placed into water to
make 150.0 mL of solution. The
solution's temperature decreases
by 8.91°C. Calculate AH, in kJ/
mol, for the dissolution of the
unknown solid. (The specific heat
of the solution is 4.184 J/g•°C
and the density of the solution is
1.02 g/mL).
