find the moles of KBr ... 5.00 g / molar mass KBr
find energy change ... 25.0 g H2O * specific heat H2O * temperature change H2O
A 5.00-g sample of KBr at 25.0 C dissolves in 25.0 mL of water also at 25.0 C. The final equilibrium temperature of the resulting solution is 18.1 C. What is the enthalpy of solution, delta H (s), of KBr expressed in kilojoules per mole? Last one on prelab got me stumped - Can't figure it out. Thanks for any help
