Step 1

Given information:

Mass of barium = 1.50 g

Mass of water = 100.00 g

Initial temperature = 22.00 C

Final temperature = 33.10 C

Specific heat of the solution = 4.18 J/g.C

Step 2

Enthalpy of solution can be determined by measuring the amount of heat (q) released and number of moles of solute (n). The expression for enthalpy can be expressed as follows:

Step 3

The amount of heat released can ...
