1kJ x 1/Hvap x g/mol liquid
The specific enthalpy of vaporization (usually represented by the letter H with a carat above it) is generally given as units of energy per unit mass or per mole. If given in terms of per unit mass, the mass boiled can be calculated by dividing the energy input by the specific enthalpy. If given in terms of per mole, first divide the energy by the specific enthalpy then multiply the result by the mass per mole.

To calculate the volume of water boiled off, you need to know the initial volume of water, the heat input, the time it was heated, and the specific heat capacity of water. You can use the equation Q = mcΔT, where Q is the heat energy, m is the mass of water, c is the specific heat capacity of water, and ΔT is the change in temperature. Once you have the heat energy, you can convert it to volume using the density of water.
After water has been boiled, its mass will stay the same.
The latent heat of vaporization (Hvap) is used to calculate the mass of liquid boiled by 1 kJ of energy using the formula: mass = energy / Hvap. This formula helps determine the amount of liquid that can be converted to vapor with a given amount of energy input.
The formula to calculate the mass of liquid boiled by 1 kJ of energy is: mass = 1 kJ / delta Hvap. ΔHvap is the molar enthalpy of vaporization, which is the amount of energy required to vaporize one mole of a substance. By dividing the energy input (1 kJ) by the enthalpy of vaporization, you can determine the mass of liquid that will be vaporized.

Grams Liquid x mol/g x Hfusion
The heat of fusion is the amount of energy needed to change a substance from a liquid to a solid. To calculate the energy released when a mass of liquid freezes, you would use the equation Q = m * Hf, where Q is the energy released, m is the mass of the substance, and Hf is the heat of fusion.
Grams liquid × mol/g × Hfusion
Stoichiometry can be used to calculate the energy absorbed when a mass melts by considering the enthalpy of fusion, which is the amount of energy required to change a substance from solid to liquid at its melting point. By using the molar mass of the substance and the enthalpy of fusion, you can calculate the amount of energy needed to melt a specific mass of the substance.
Stoichiometry can be used to calculate the energy released when a mass of liquid freezes by accounting for the heat of fusion of the substance. By calculating the amount of heat energy required to freeze the liquid based on its specific heat capacity and mass, you can determine the energy released during the phase change. This can be expressed through the equation Q = m * h_f, where Q is the energy released, m is the mass of the substance, and h_f is the heat of fusion constant.
Grams liquid × mol/g × Hvap
Stoichiometry can be used to determine the amount of heat energy released during the freezing of a liquid by relating the quantity of the substance that freezes to the heat of fusion of the substance. This involves multiplying the mass of the liquid that freezes by the heat of fusion value to calculate the total energy released. This calculation helps in understanding the energy changes that occur during phase transitions like freezing.
