Mole Conversions

Front

What is a mole?

Back

A mole is a unit of measurement in chemistry that represents 6.02 x 10^23 particles (atoms, molecules, ions, etc.).

Front

What is molar mass?

Back

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

Front

How do you convert moles to grams?

Back

To convert moles to grams, multiply the number of moles by the molar mass of the substance: grams = moles x molar mass.

Front

What is Avogadro's number?

Back

Avogadro's number is 6.02 x 10^23, which is the number of particles in one mole of a substance.

Front

What is the molar mass of carbon (C)?

Back

The molar mass of carbon is approximately 12.01 g/mol.

Front

How many grams are in 2 moles of NaCl?

Back

To find the grams in 2 moles of NaCl, first find the molar mass (58.44 g/mol), then multiply: 2 moles x 58.44 g/mol = 116.88 g.

Front

What is the relationship between grams and moles?

Back

Grams and moles are related through the molar mass of a substance, allowing conversion between the two.

Front

What is the molar mass of water (H2O)?

Back

The molar mass of water is approximately 18.02 g/mol.

Front

How do you find the number of molecules in a given mass of a substance?

Back

To find the number of molecules, divide the mass of the substance by its molar mass to find moles, then multiply by Avogadro's number.
