How many different types of calculations are present that are based on chemical equation?

The correct answer is: 4

When carrying out calculations based on chemical equations, the coefficients of a balanced chemical equation are very important. With these coefficients, we can write a ratio of any two or more substances in the chemical equation. This is known as reaction stoichiometry.
¶The reaction stoichiometry is the mole ratio of all the reactants and products in the reaction.
