HEAT (ENTHALPY) OF SOLUTION: DEFINITION, FORMULA, & PROBLEMS

Web Calculate the heat of solution when 50 g of hydrated salt is dissolved in 100 g of water, resulting in a temperature increase of 20 °C. The specific heat of water is 4.184 J/g-°C. Solution. Given m = 50 g + 100 g = 150 g c p = 4.184 J/g-°C ΔT = 20 °C The heat of solution is ΔH soln = m x c p x ΔT => ΔH soln = 150 g x 4.184 J/g-°C x 20 °C
