What amount of heat must be transferred to acetone of mass m = 2.0 g at the boiling point in order to transfer it to a gaseous state?

Initial data: m (weight of acetone) = 2 g; acetone is at boiling point.

Reference values: L (specific heat of vaporization of acetone) = 525 kJ / kg = 525 * 10 ^ 3 J / kg.

SI system: m = 2 g = 2 * 10 ^ -3 kg.

The amount of heat that needs to be transferred to acetone is calculated by the formula: Q = L * m.

Let’s perform the calculation: Q = 525 * 10 ^ 3 * 2 * 10 ^ -3 = 525 * 2 = 1050 J.

Answer: To convert acetone to a gaseous state, it needs to transfer 1050 J of heat.
