The Mole

Different atoms have different masses.

1g of carbon has far fewer atoms than 1g of hydrogen atoms.

Chemists need a method of quantifying atoms.

We use a quantity called the amount of substance which is measured in moles.

One mole contains 6.02 x 10²³ particles.

The relative atomic mass is the mass of one mole of that element’s atoms.

The relative molecular mass is the mass of one mole of molecules
