Approximate atomic weight of an element ...

Approximate atomic weight of an element is `26.89`. If its equivalent weight is `8.9`, the exact atomic weight of element would be

A

26.89

B

8.9

C

17.8

D

26.7

Text Solution

Verified by Experts

The correct Answer is:
D
Atomic weight = Equivalent weight × Valency
` = 8.9 xx 3 = 26.7 ( "Valency" + (26.93)/(8.9) ~~3 )`
