Answer 1

1)

Equivalent weight of Fe2+ = Molar mass/valency = 55.85/2 = 27.925 g/eq OR 27.925*1000/1000 mg/meq = 27.925 mg/meq

Now,

1 miliequivalent contains 27.925 miligrams

So, 6 meq will contain = 6 * 27.925 = 167.55 miligrams ....Answer

2)

Equivalent weight of CaCO3 = Molar mass/charge on cation or anion = 40 + 60 / 2 = 50 g/Eq = 50*1000/1000 mg/mEq = 50 mg/mEq

So, 8 mEq = 8 * 50 = 400 mg ...Answer

3) Equivalent weight = 120/2 = 60 g/Eq

60 g = 1 Eq

So, 6 g = 6/60 = 0.1 Eq = 0.1 * 1000 = 100 mEq ...Answer

Let me know if any doubts.
