Homework Help: Chemistry

Posted by Bob on Monday, April 18, 2011 at 4:20pm.

If you were to prepare a 1.00 molal solution of CaCl2 beginning with water at 27.0 C, what would the final temperature of the solution be (in C)? Assume that the specific heats of both pure H2O and the solution are the same, 4.18 J/K*g.

The dissolution of CaCl2 in water is exothermic, with deltaH soln = -81.3 kJ/mol.
