Explanation & Answer
Attached.
1. Concentration of H2O2 = 0.875 M
Initial temperature = 21.5 ℃
Final temperature = 37 ℃
So, ∆T = 37 − 21.5 = 15.5℃
Specific heat of solution = 4.179 J/g℃
Density of the solution = 1g/ml
Volume of the solution = 60 ml
Heat change of solution:

J
∆q = 1 × 60ml × 4.179
× 15.5℃ = 3886.47J
