Moles to grams and grams to moles

Front

What is a mole in chemistry?

Back

A mole is a unit of measurement used to express the amount of a substance. It is defined as the amount of substance that contains as many entities (atoms, molecules, etc.) as there are in 12 grams of carbon-12.

How do you convert moles to grams?

Back

To convert moles to grams, use the formula: grams = moles × molar mass. The molar mass is the mass of one mole of a substance, usually expressed in grams per mole (g/mol).

What is the molar mass of potassium permanganate (KMnO4)?

Back

The molar mass of KMnO4 is approximately 158.04 g/mol.

Front

How do you calculate the mass of a substance from moles?

Back

Multiply the number of moles by the molar mass of the substance: mass (g) = moles × molar mass (g/mol).

Back

The molar mass of Co(NO3)2 is approximately 182.9 g/mol.

Front

How do you convert grams to moles?

Back

To convert grams to moles, use the formula: moles = grams / molar mass.
