Calculate the standard enthalpy change ($\Delta H^\circ$) for the dissolution of 10.0 g of sodium hydroxide (NaOH) in 100.0 mL of water assuming that the specific heat capacity of the solution is 4.18 J g$^{-1}$ K$^{-1}$ and that the initial and final temperatures are 25.0$^\circ$C and 35.0$^\circ$C, respectively. The molar mass of NaOH is 40.0 g mol$^{-1}$.
