Stoichiometry moles to mass

Front

What is the conversion factor between mole and atoms?

Back

1 mole = 6.022 x 10^23 atoms/particles.

Front

When calculating the molar ratio, we use the

Back

Coefficients.

Front

The relationship between two units being converted is called the

Back

Conversion factor.

Front

What is the molar mass for water (H2O)?

Back

18.02 g/mol.

Front

What is the molar ratio between oxygen and magnesium oxide in the reaction 2 Mg + O2 -> 2 MgO?

Back

1 mol O2 : 2 mol MgO.

Front

Define molar mass.

Back

The mass of one mole of a substance, typically expressed in grams per mole (g/mol).

Front

What is Avogadro's number?

Back

6.022 x 10^23, the number of atoms or molecules in one mole of a substance.

Front

How do you calculate the number of moles from mass?

Back

Number of moles = mass (g) / molar mass (g/mol).

Front

What is the significance of coefficients in a balanced chemical equation?

Back

They represent the molar ratios of reactants and products.

Front

What is a limiting reagent?

Back

The reactant that is completely consumed in a chemical reaction, limiting the amount of product formed.
