Question

When a 8.00 g sample of KCN is dissolved in water in a calorimeter that has a total heat capacity of 3.19 kJ⋅K−1, the temperature decreases by 0.450 K. Calculate the molar heat of solution of KCN.

Δsoln= __________ kJ/mol

Answer 1

So you divide 8.00 by 3.19 and then the result that you get from that you can multiply with 0.450.
