Question

If the equivalent weight of a metal oxide is 20, then equivalent weight of its nitride will be

Answer 1

Given,
equivalent weight of a metal oxide = 20
we know,
equivalent weight of metal + equivalent weight of oxide = equivalent weight of metal oxide

equivalent weight of oxygen = 8
equivalent weight of nitrogen = 14/3 ≈ 4.67

equivalent weight of metal + 8 = 20
equivalent weight of metal = 12

now, equivalent weight of metal nitride = equivalent weight of metal + equivalent weight of nitrogen
= 12 + 4.67 = 16.67

hence, equivalent weight of nitride= 16.67
