Chapter 11, Problem 56A

Interpretation Introduction

Interpretation:

The law on which all the stoichiometry equations are based on needs to be explained.

Concept introduction:

The stoichiometric calculations are based on mole concept. They are based on different steps like calculation of mass and moles. Interpret the mole ratio and further calculate the mass of desired product. The mole concept provides relation between moles, mass and molar mass.

Answer to Problem 56A

The stoichiometry calculations are based on the Law of conservation of mass.

Explanation of Solution

The first step of all the stoichiometric calculations is writing the balanced chemical equation for the given chemical reaction as balanced chemical equation provide idea about the mole ratio of reactant and product molecules. The stoichiometry calculation are based on the Law of conservation of mass. It states that the mass of substances before and after the reaction. In other words, the sum of reactants will equal the sum of products.
