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?
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
