MCQ
A compound $MX_2$ has observed and normal molecular masses $65.6$ and $164$ respectively. Calculate percentage of ionization of $MX_2$ ............ $\%$
- A$75$
- ✓$65$
- C$55$
- D$35$
✓
Answer
Correct option: B.
$65$
b
$\frac{\mathrm{W}}{\mathrm{W}+60} \times 100=20$
$\frac{\mathrm{W}}{\mathrm{W}+60} \times 100=20$
$5 \,\mathrm{W}=\mathrm{W}+60$
$4\, \mathrm{W}=60$
$\mathrm{W}=15\, \mathrm{g}$
