Unit conversion factors are used to convert between units of grams and moles.
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.
Grams liquid × mol/g × Hfusion
Stoichiometry can be used to calculate the energy absorbed when a mass of a solid melts by considering the heat energy required to overcome the intermolecular forces holding the solid together. By using the heat capacity of the solid, the mass of the solid, and the enthalpy of fusion for the substance, stoichiometry can help determine the amount of energy needed for the solid to melt.
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.
Stoichiometry is used to calculate the amounts of reactants and products in a chemical reaction by using the balanced chemical equation. This involves converting the given quantity of one substance to another using mole ratios, and then using the molar mass to convert between moles and mass. This process allows for the determination of the amounts of substances involved in the reaction.

Stoichiometry is used to calculate the mass of a substance by utilizing the relationships between the amounts of reactants and products in a chemical reaction, as defined by the balanced chemical equation. By converting moles of one substance to moles of another using the mole ratios from the equation, we can then apply the molar mass of the desired substance to find its mass. This process allows chemists to predict how much of a substance will be produced or consumed in a reaction, facilitating accurate measurements in laboratory settings.

While molar mass is not a conversion factor itself in stoichiometry, it plays a crucial role in converting between grams and moles of a substance. Molar mass is used to convert the mass of a substance to moles, enabling the stoichiometry calculations that involve mole ratios in chemical reactions.

Grams solid × mol/g × Hfusion
Stoichiometry can be used to calculate the energy released during the freezing of a liquid by calculating the moles of the liquid that freeze and then using the enthalpy of fusion of the substance (given in kJ/mol) to determine the total energy released during the process. The energy released can be found by multiplying the moles of liquid that freeze by the enthalpy of fusion value.
