The oxide of a metal contains \(40 \%\) of oxygen. The valency of metal is 2 . What is the atomic weight of metal?
- A \(24\)
- B \(13\)
- C \(40\)
- D \(36\)
Answer & Solution
Correct Answer
(A) \(24\)
Step-by-step Solution
Detailed explanation
\(\because 40 \mathrm{~g}\) of oxygen is combined with \(=60 \mathrm{~g}\) of metal \[ \begin{array}{r} \therefore 8 \mathrm{~g} \text { of oxygen will be combined with }=\frac{60 \times 8}{40} \\ =12 \mathrm{~g} \text { of metal } \end{array} \] \(\therefore\) Equivalent weight…
