More material per mole can be found in helium.

The unit of measurement for quantity is the mole. Things react in straightforward mole ratios. However, as balances do not provide readings in moles, you must convert them into grams when comparing the amount of one material to another using moles.

To convert molecular weights to grams, follow these three procedures.

1. Determine the number of moles mentioned in the question.

2. Determine the substance's molar mass.

3. Multiply the two figures.

Avogadro's number of atoms makes up one mole. The amount of a mole can be translated to grams if you know how many there are, and vice versa.

80g/4g/mol helium = 20 Mol

400g/40g/mol of argon = 10 mol
