Question

When a 15.3 g sample of KOH dissolves in 70.0 g of water in a calorimeter, the temperature rises from 22.4 ˚C to 66.4 ˚C. Calculate ΔH for the process and write it on the correct side of the equation.

  • Hi. It's seems like the problem is missing some information. Is there a heat capacity given for the solutions and calorimeter somewhere? Pat commented over 1 year ago
  • I am sorry, I can not find other information. but other problems, they assume that the density and specific heat of all solutions are the same as water. In Kyung commented over 1 year ago
