Question: A 0.757 g sample of solid LiBr (s) is dissolved in 442 mL of water in a coffee cup calorimeter. Once all of the LiBr

A 0.757 g sample of solid LiBr (s) is dissolved in 442 mL of water in a coffee cup calorimeter. Once all of the LiBr (s) is dissolved in the water, the final temperature of the solution is found to be 26.4C. If the initial temperature of the water in the calorimeter was 21.9 C, calculate the calorimeter constant (in J/K) for the coffee cup calorimeter.

Report your answer to three significant figures.

The heat of solvation of LiBr (s) is -48.83 kJ/mol.
