Question:
10 g of a metal (M) reacts with oxygen to form 11.6 g of oxide. What is the equivalent weight of \( M \)?
10 g of a metal (M) reacts with oxygen to form 11.6 g of oxide. What is the equivalent weight of \( M \)?
Show Hint
Equivalent weight can be found using the relation \( E = \frac{\text{Mass of metal}}{\text{Mass of oxygen}} \times 8 \).
Updated On: Jan 6, 2026
- \( 50 \) g
- \( 0.02 \)
- \( 0.02 \) g
- \( 50 \)

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Oxygen Mass
Mass of oxygen in metal oxide:
\[
\text{Mass of oxygen} = 11.6 - 10 = 1.6 \text{ g}
\]
Step 2: Equivalent Weight Formula \[ \text{Equivalent weight} = \frac{\text{Mass of metal}}{\text{Mass of oxygen}} \times 8 \] \[ = \frac{10}{1.6} \times 8 = 50 \]
Step 2: Equivalent Weight Formula \[ \text{Equivalent weight} = \frac{\text{Mass of metal}}{\text{Mass of oxygen}} \times 8 \] \[ = \frac{10}{1.6} \times 8 = 50 \]
