Question

H2o has a delta.hvap = 40.7 kj/mol. what is the quantity of heat that is released when 27.9 g of h2o condenses? use q equals n delta h.. 60.00 kj 61.05 kj 63.09 kj 68.60 kj

Answer 1

63.09 kJ is the amount of energy calculated.

A substance's physical characteristic is its latent heat of vaporization. Its definition is the amount of heat needed to transform a single mole of liquid at its boiling point at mean atmospheric pressure. Using the specific latent heat of vaporization, one may compute the amount of energy released as a substance transition from its gaseous state to its liquid state. A substance's physical characteristic is its latent heat of vaporization. The energy absorbed during the process is known as the latent heat of vaporization. When a substance in the liquid state is supplied energy, it changes its phase from liquid to vapour without changing its temperature. These calculations are made:

Energy is calculated as 27.9 g (1 mol / 18.02 g) x 40.7 kJ/mol.

63.09 kJ = energy
