Molar Conversions

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.

To calculate the mass of a substance from moles, use the formula: Mass (g) = Moles × Molar Mass (g/mol).

The molar mass of water (H₂O) is approximately 18 g/mol.

1 mole of carbon (C) has a mass of approximately 12 g.

The molar mass of magnesium (Mg) is approximately 24 g/mol.

To convert grams to moles, use the formula: Moles = Mass (g) / Molar Mass (g/mol).

The mass of 4.0 moles of water (H₂O) is 72 g.

There are approximately 3.67 moles in 88.1 grams of magnesium.

The mass of one mole of gold(III) chloride (AuCl₃) is 303 g.

There are approximately 0.55 moles in 22 grams of argon (Ar).
