MCQ
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
    $17.8$
  • ✓
    $26.7$
✓

Answer

Correct option: D.
$26.7$
d
(d) Atomic weight = Equivalent weight $\times$ Valency

$ = 8.9 \times 3 = 26.7$ $\left( {{\rm{Valency}} = \frac{{{\rm{26}}{\rm{.89}}}}{{{\rm{8}}{\rm{.9}}}} \approx 3} \right)$.
