When a 130 G Sample of NaOHs) Dissolves in 400 $\degree$

When a 13.0 g sample of NaOHs) dissolves in 400.0 mL of water to produce 413.0 g of solution in a constant pressure calorimeter, the temperature of the water and reaction vessel changes from 22.6 $\degree$ C to 30.6 $\degree$ C.Assume that the specific heat capacity of the solution is 4.2 J/(g . $\degree$ C) , and that the heat capacity of the reaction vessel is 1.00 J/ $\degree$ C.What is the molar enthalpy of solution of sodium hydroxide (40.00 g/mol) ?

A) (-34 kJ/mol)
B) (-54 kJ/mol)
C) (-17 kJ/mol)
D) (-43 kJ/mol)
E) (-14 kJ/mol)
