10.0 g (0.385 mol) of a new salt dissolves in enough water to make 75.0 g of total solution (salt and water). From the dissolving process, the solution increases in
temperature by 12.2°C. What is the enthalpy of solution for this new salt (AH soln)?
Assume the specific heat capacity of the solution is 4.20 J g 10c-1.
0 -9.98 kJ/mol
0 -3.84 kJ/mol
O +3.94 kJ/mol
0 -0.148 kJ/mol
+9.98 kJ/mol
