Options
A Heat required to raise 1 g by 1°C
B Heat required to raise 1 mole of the substance through 1°C
Correct Answer
C Total heat of reaction
D Heat of formation
Correct Answer

Option B is the correct answer.

Detailed Explanation

Molar heat capacity Cₘ is the amount of heat required to raise 1 mole of the substance through 1°C (or 1 K). Cₘ = q/(n·ΔT). Unit: J·mol⁻¹·K⁻¹ or J·mol⁻¹·°C⁻¹.

Hint

The notes define molar heat capacity.
