We have to convert 0.00101 mol of iron(II) sulfate, FeSO4_4 to grams using average atomic masses given in periodic table. Molar mass is the mass of 1 mol of substance.

Known from periodic table: ArAr(Fe)=55.85 g/mol ArAr(S)=32.07 g/mol ArAr(O)=16.00 g/mol

The molar mass of molecule is calculated by summing the average atomic masses (in g/mol) of the constituent atoms.
