The enthalpy of vaporization of liquid water is 40.65 kJ/mol. Calculate the energy required to vaporize 12.5 g of liquid water.

The energy required to vaporize 12.5 g of liquid water is 28.2 kJ

Explanation:

Latent heat of vaporization is the amount of heat required to convert 1 gram of liquid into its vapor state without change in its temperature.

Given : The enthalpy of vaporization of water is 40.65 kJ/mol.

n = number of moles =

Thus 1 mole of water requires heat = 40.65 kJ

0.694 moles of water requires heat =

Thus the energy required to vaporize 12.5 g of liquid water is 28.2 kJ

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.

explanation:

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
