A 25.00 gram sample of barium chloride was dissolved in 75.00 grams of water. If the calorimeter constant, K_c , is 120 J/ celsius, how much heat is produced by the dissolution (absorbed from the solution) if the temperature goes from 18.00 degrees celsius to 0.55 degrees celsius. Assume the specific heat of the solution is 4.18 J/ g degrees celsius.

What is the enthalpy of solvation of the salt lithium chloride (LiCl)?

mass of water in calorimeter = 18.825 g

mass of the solid salt dissolved= 5.833 g

initial temperature of water = 20 degrees celsius

final temperature of water = 59.5 degrees celsius

the salt starts at room temperature (20 degrees celsius) and the final temperature is 59.5 degrees celsius

the specific heat capcity of water is 4.18 J/(g degrees celsius)

If 1.35g of potassium chloride is dissolved in 10.27g of water, and the temperature of the water increased by 2.13 degrees celsius, what is the heat of the solution? The specific heat capacity of the solution is close to that of water and can be called 4.18 J/g degree celsius.
