MCQ
Mass of $NaOH$ required for formation of $100\, ml$ of its decimolar solution is .............. $\mathrm{g}$
- A$0.8$
- ✓$0.4$
- C$0.2$
- D$8$
✓
Answer
Correct option: B.
$0.4$
b
$\frac{1}{{10}} = \frac{{W \times 1000}}{{100 \times 40}}$
$\frac{1}{{10}} = \frac{{W \times 1000}}{{100 \times 40}}$
$W = 0.4\,g$
