Mole-Mole Stoichiometry

Front

What is mole-mole stoichiometry?

Back

Mole-mole stoichiometry is a method used in chemistry to calculate the amounts of reactants and products in a chemical reaction based on the balanced chemical equation.

What is a balanced chemical equation?

Back

A balanced chemical equation is an equation that shows the reactants and products of a chemical reaction with equal numbers of each type of atom on both sides.

What is Avogadro's number?

Back

Avogadro's number is 6.022 x 10^23, which is the number of particles (atoms, molecules, etc.) in one mole of a substance.

Front

How do you find the number of moles of a product?

Back

To find the number of moles of a product, use the mole ratio from the balanced chemical equation and the number of moles of the reactant.

What is the mole ratio in the reaction 4NH3 + 5O2 -> 4NO + 6H2O?

Back

The mole ratio of NH3 to H2O is 4:6, which simplifies to 2:3.

Front

If 12 moles of NH3 are consumed, how many moles of H2O are produced?

Back

18 moles of H2O are produced.

In the reaction 6CO2 + 6H2O -> C6H12O6 + 6O2, how many moles of water are needed to produce 2.5 moles of glucose?

Back

15 moles of water are needed.

Front

What is the significance of mole ratios?

Back

Mole ratios are used to determine how much of one substance is needed to react with or produce another substance in a chemical reaction.

Front

What is the relationship between moles and mass?

Back

The number of moles of a substance can be calculated by dividing its mass (in grams) by its molar mass (in g/mol).
