Question

(ii) Atomic mass of an element is equal to:

(A) Equivalent mass X Valency

(B) Equivalent mass/valency

(C) (Equivalent mss)n where n is the valency.

(D) None of these​

Answer 1

1.the atomic mass of an element, measured in amu, is the same as the mass in grams of one mole of an element.

2.The equivalent weight of an element or radical is equal to its atomic weight or formula weight divided by the valence it assumes in compounds.

3.The unit of equivalent weight is the atomic mass unit; the amount of a substance in grams numerically equal to the equivalent weight is called a gram equivalent.

4.For an element, the atomic weight is equal to the product of equivalent weight and valency.

A=E×n

In the other word, the equivalent weight is the ratio of atomic weight to valency

E=

n

A

Answer 2

Equivalent mass X Valency
