Calculate the enthalpy change for the dissolution of 5.00 g of sodium hydroxide (NaOH) in 100.0 g of water (H2O). The temperature change was measured to be -3.45°C. Given that the specific heat of water is 4.18 J/g°C and the density of water is 1.00 g/mL. (Assume that the heat evolved from NaOH is absorbed by the water.)
