Interpretation: The reason for balancing a chemical equation before determining the mole ratio needs to be explained.
Concept introduction: The ratio of the mass of a substance to its molar mass is said to be the number of moles of that substance.
The ratio of the amount of any two compounds involved in a
Explanation of Solution
The law of conservation of mass explained that the quantity of each element involved in the reaction should remain constant throughout a chemical reaction so that the quantity of each element involved in the reaction is balanced in each side of a chemical equation. In order to balance the reactions, coefficients are used. The mole ratios are determined from the coefficients of a balanced chemical equation. The mole ratio of an unbalanced equation cannot be used to determine the relationship between reactants and products. Hence, it is necessary to balance the chemical equation before determining the mole ratio.
