How is the measurement unit, the mole, different from the measurement unit, the kilogram?

A 110 g copper bowl contains 240 g of water, both at 21.0°C. A very hot 410 g copper cylinder is dropped into the water, causing the water to boil, with 8.60 g being converted to steam. The final temperature of the system is 100°C.

A quantity of 1.922 g of methanol (CH3OH) was burned in a constant-volume bomb calorimeter. Consequently, the temperature rose by 5.72°C. If the heat capacity of the bomb plus water was 9.
