Two oxides of a \(X\) contain \(50 \%\) and \(40 \%\) of non-metal respectively. If the formula of the first oxide is \(\mathrm{XO}_2\). Then the formula of second oxide is
- A \(X_2 \mathrm{O}_3\)
- B \(X_2 \mathrm{O}_5\)
- C \(X \mathrm{O}_3\)
- D \(X_2 \mathrm{O}\)
Answer & Solution
Correct Answer
(C) \(X \mathrm{O}_3\)
Step-by-step Solution
Detailed explanation
In \(\mathrm{XO}_2, \mathrm{X}: \mathrm{O}:: 50: 50\) Mass of oxygen \(=2 \times 16=32 \mathrm{~g}\) Hence, mass of \(X=32 \mathrm{~g}\) In \(\mathrm{XO}_n, \mathrm{X}: \mathrm{O}:: 40: 60\) Mass of \(X\), in this case also remains \(=32 \mathrm{~g}\)…
