Multiply the number of particles by $$6.02\times10^{23}$$

Divide the number of particles by $$6.02\times10^{23}$$

Add $$6.02\times10^{23}$$

Multiply the number of particles by the molar mass

The mole is used to relate macroscopic quantities of a substance to microscopic particles.

The mole is only used for gases.

The mole is a unit for measuring volume, not mass.

The number of moles is irrelevant when calculating molecular formulas.
