10 g of a metal (M) reacts with oxygen to form 11.6 g of onide. What is the equivalent weight of M?
10 g of a metal (M) reacts with oxygen to form 11.6 g of onide. What is the equivalent weight of M?
- 50 g
- 0.02
- 0.02 g
- 50
Solution
$\begin{aligned}
& \text { Equivalent weight of metal } \\
& =\left(\frac{10}{11.6-10}\right) \times 8 \\
& \\
& =\frac{10}{1.6} \times 8 \\
& \\
& =50
\end{aligned}$
$\left[\begin{array}{rl}
\text { NOTE } & \rightarrow \text { Equivalent weight of metal } \\
& =\frac{\text { Mass of metal }}{\text { Mass of oxygen }} \times \text { Equivalent weight }(\text { oxygen })
\end{array}\right]$
