An oxide of the element contains \(20 \% \mathrm{O}_{2}\) by weight. Calculate the equivalent weight of the element.
- A 8
- B 16
- C 32
- D 12
Answer & Solution
Correct Answer
(C) 32
Step-by-step Solution
Detailed explanation
Gram equivalent of element \(=\) Gram equivalent of \(\mathrm{O}_{2}\) \(\frac{80}{E}=\frac{20}{8}\)
\[
E=32
\]
\[
E=32
\]
