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.

Front

What does the coefficient in a chemical equation represent?

Back

The coefficient in a chemical equation represents the number of moles of a substance involved in the reaction.

Front

How many moles of ammonia are produced from 3 moles of nitrogen in the reaction N2 + 3H2 -> 2NH3?

Back

6 moles of ammonia are produced.

Front

What is a mole ratio?

Back

A mole ratio is a ratio that compares the number of moles of one substance to the number of moles of another substance in a chemical reaction.

Front

What is the mole ratio of H2O to H3PO4 in the reaction P4O10 + 6 H2O -> 4 H3PO4?

Back

The mole ratio is 6:4.

Front

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 determine the mole ratio from a balanced equation?

Back

You determine the mole ratio by looking at the coefficients of the reactants and products in the balanced chemical equation.

Front

What is the mole ratio of silver nitrate to copper(II) nitrate in the reaction 2AgNO3 + Cu -> Cu(NO3)2 + 2Ag?

Back

The mole ratio is 2 mol AgNO3 / 1 mol Cu(NO3)2.

Front

What is the significance of mole ratios in stoichiometry?

Back

Mole ratios are significant in stoichiometry because they allow chemists to predict the amounts of reactants needed and products formed in a chemical reaction.
