A generic solid X has a molar mass of 68.1 g/mol. In a constant-pressure calorimeter 44.6 g of X is dissolved in 301 g of water at 23.00 °C.
X(s)--> X(aq)
The temperature of the resulting solution rises to 26.10 °C. Presume the solution has the same specific heat as water 4.184 J/(g•°C) as well as that there's negligible heat loss to the surroundings. Explain how much heat was absorbed by the solution? Explain what is the enthalpy of the reaction?
