1.75g CaCl2 dissolves 125g H2O in calorimeter, temp increases 2.44 degrees. what is heat change per mol of CaCl2 (C=4.18 J/g degree C?

An ionic solid is dissolved in a beaker of water at room temperature. After the crystals have dissolved, the sides of the beaker feel cold. State the thermochemical term for the type of process involved, and identify the sign of the enthalpy change.

I need help solving this problem. Greatly appreciate it if you can help me show the step by step process for me to learn
