Use H = 1, N = 14, O = 16, S = 32, Fe = 56. Mohr's salt, $FeSO X_{4} \cdot (NH X_{4}) X_{2} SO X_{4} \cdot 6 H X_{2} O$ , is titrated with acidified $KMnO X_{4}$ . Its equivalent mass is:

Only

Fe X^{2 +} Fe X^{3 +}

changes, so

n = 1

. Molar mass

= 56 + 96 + 36 + 96 + 108 = 392

, equal to equivalent mass.
