Reference: AQA
Multiplying the amount in moles by 6.02 × 10²³ gives the number of particles, and dividing the number of particles by 6.02 × 10²³ gives the amount in moles.
The amount in moles is found from the mass of a substance using moles = mass ÷ relative formula mass, or from a concentration and volume for a solution.
Converting solute mass into moles using moles = mass ÷ relative formula mass before finding concentration.
