Answer:

3.53 g

Explanation:

To convert from atoms to moles, you need to know Avogadro's number.  Avogadro's number (6.022 × 10²³) is how many atoms there are in one mole of a substance.  Use this to convert.

(1.97 × 10²² atoms) ÷ (6.022 × 10²³ atoms/mol) = 0.0327 mol

Now that you have moles, use the molar mass to convert to grams.

(0.0327 mol) × (107.87 g/mol) = 3.53 g

Answer:

The mass of a pure substance represents a specific number of pure substance 'molecules', as defined by molecular weight. The relative atomic mass (atomic weight) in grams/mole (g/mol) is the molar mass of a substance, which means it is the mass of one mole of that substance.

So what have I done here? First, I had a balanced chemical equation (this is the important step; is it balanced?). Then I used the stoichiometry to get the molar quantity of product, and converted this molar quantity to mass. If this is not clear, I am willing to have another go
