Moles and 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 the molar mass of a substance?

Back

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

Front

How do you convert grams to moles?

Back

To convert grams to moles, divide the mass of the substance (in grams) by its molar mass (in g/mol).

Front

How do you convert liters of gas to moles at STP?

Back

At Standard Temperature and Pressure (STP), 1 mole of gas occupies 22.4 liters. To convert liters to moles, divide the volume (in liters) by 22.4 L/mol.
