## Can you use stoichiometric relationships in calculations?

Key Terms. stoichiometric ratio: The ratio of the coefficients of the products and reactants in a balanced reaction. This ratio can be used to calculate the amount of products or reactants produced or used in a reaction.

**How do you find stoichiometric coefficients?**

Stoichiometric Coefficients If we know how many moles of Na we start out with, we can use the ratio of 2 moles of NaCl to 2 moles of Na to determine how many moles of NaCl were produced or we can use the ration of 1 mole of H2 to 2 moles of Na to convert to NaCl. This is known as the coefficient factor.

**Why is a balanced chemical equation needed for stoichiometric calculations?**

All stoichiometric calculations begin with a balanced equation. Balanced equations are necessary because mass is conserved in every reaction. The number and kinds of atoms must be the same in the reactants and products. In mass calculations, the molar mass is needed to convert mass to moles.

### Why is limiting reactant essential in stoichiometric calculations?

Essential of limiting reagent : Limiting reagent is essential in stoichiometric calculation because of the following reasons: It gives the information about the given chemical reaction and helps in a number of chemical calculations. It helps to calculate a number of products formed.

**Why is a balanced chemical equation needed in solving stoichiometric calculations?**

All stoichiometric calculations begin with a balanced equation. Balanced equations are necessary because mass is conserved in every reaction. The number and kinds of atoms must be the same in the reactants and products.

**Which law has to be obeyed during stoichiometric calculations explain with an example?**

Ans: Law of conservation of mass must be obeyed while doing stoichiometric calculations.

## What law are all stoichiometric calculations based on?

the law of conservation of mass

The principles of stoichiometry are based upon the law of conservation of mass. Matter can neither be created nor destroyed, so the mass of every element present in the product(s) of a chemical reaction must be equal to the mass of each and every element present in the reactant(s).
