an iron supplement is used to treat anaemia and 50mg of iron 2 is required per tablet.if the iron compound used in the tablet is FeSO4.7H2O,what mass of this compound would be required per tablet to provide the desired amount of iron 2?

Answer 1

50 mg Fe x (molar mass FeSO4.7H2O/atomic mass Fe) = ?mg FeSO4.7H2O is what the final equation is.
Intermediate equation is
50 mg Fe x (1 mol Fe/atomic mass Fe) x (1 mol FeSO4.7H2O/1 mol Fe) x (molar mass FeSO4.7H2O/1mol FeSO4.7H2O) = ? mg FeSO4.7H2O
