A student investigates the enthalpy of solution, ΔHsoln, for two alkali metal halides, KCl and RbCl. Inaddition to the salts, the students has access to a calorimeter, a balance with a precision of ±0.1 g,and a thermometer with a precision of ±0.1°C.a. To measure ΔHsoln for KCl, the student adds 100.0 g of water initially at 25.0°C to acalorimeter and adds 20.0 g of KCl(s), stirring to dissolve. After the KCl dissolvescompletely, the maximum temperature reached by the solution is 55.4°C.i. Calculate the magnitude of the heat absorbed by the solution during the dissolutionprocess, assuming that the specific heat capacity of the solution is 4.18 J/(g*°C).Include units with your answer.

Question

A student investigates the enthalpy of solution, ΔHsoln, for two alkali metal halides, KCl and RbCl. In
addition to the salts, the students has access to a calorimeter, a balance with a precision of ±0.1 g,
and a thermometer with a precision of ±0.1°C.
a. To measure ΔHsoln for KCl, the student adds 100.0 g of water initially at 25.0°C to a
calorimeter and adds 20.0 g of KCl(s), stirring to dissolve. After the KCl dissolves
completely, the maximum temperature reached by the solution is 55.4°C.
i. Calculate the magnitude of the heat absorbed by the solution during the dissolution
process, assuming that the specific heat capacity of the solution is 4.18 J/(g*°C).
Include units with your answer.
