Webassign help:
How much energy is involved in the dissolving of sodium hydroxide in water? The table shows data from an experiment in which a measured amount of NaOH is dissolved in water in a foam cup calorimeter. Calculate ΔH for the process in kJ/mol. If the enthalpy change for the solution of NaOH is -44.87 kJ/mol, what is the percent error of the experiment?

mass of water: 99.6 grams
mass of NaOH: 4.01 grams
change in temperature of water: 10.4 degrees
