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.

How is the H fusion used to calculate the energy needed to melt a mass of solid?
The heat fusion (H fusion) is the amount of energy required to change a substance from solid to liquid at its melting point. To calculate the energy needed to melt a mass of solid, you multiply the mass of the substance by its heat of fusion. The formula used is ( Q = m \cdot H_f ), where ( Q ) is the energy required, ( m ) is the mass, and ( H_f ) is the heat of fusion. This calculation provides the total energy needed to completely melt the solid into a liquid at its melting temperature.
