Mole Ratios and Mole to Mole Calculations

What is a mole ratio?

• The ratio between the amounts in grams of any two compounds involved in a chemical reaction.

• The ratio between the amounts in moles of any two compounds involved in a chemical reaction.

• The ratio between the amounts in liters of any two compounds involved in a chemical reaction.

• The ratio between the amounts in moles of any two elements in a compound.

How do you determine the mole ratio between two substances in a chemical equation?

• By calculating the molar masses of the substances.

• By measuring the volume of the substances.

• By analyzing the color change in the reaction.

• By comparing the coefficients of the balanced equation.

What is a mole to mole calculation?

• A mole to mole calculation is a stoichiometric calculation that involves converting the number of moles of one substance to the number of moles of another substance using the balanced chemical equation.

• A mole to mole calculation is a technique used to balance chemical equations.

• A mole to mole calculation is a process of converting the number of atoms of one element to the number of atoms of another element.

• A mole to mole calculation is a method used to determine the mass of a substance in a chemical reaction.

How do you perform a mole to mole calculation?

• Use the volume ratio from the balanced chemical equation to convert moles of one substance to moles of another substance.
