Acoffee-cup calorimeter initially contains g water at . potassium bromide ( g), also at , is added to the water, and after the dissolves, the final temperature is . calculate the enthalpy change for dissolving the salt in j/g and kj/mol. assume that the specific heat capacity of the solution is and that no heat is transferred to the surroundings or to the calorimeter
the correct answer is a delta.
a.) atmospheric pressure
