What is the mole ratio in a chemical reaction?

Back

The mole ratio is the ratio of moles of one substance to the moles of another substance in a balanced chemical equation.

Front

How do you calculate molar mass?

Back

To calculate molar mass, sum the atomic masses of all atoms in a molecule based on the periodic table.
