MCQ
$2.76 \,g$ of silver carbonate on being strongly heated yield a residue weighing ........... $\mathrm{g}$
- ✓$2.16$
- B$2.48$
- C$2.64$
- D$2.32$
$2 \times 276\,gm$ of $A{g_2}C{O_3}$ gives $4 \times 108\,gm$
$\therefore $ $1\,gm$ of $A{g_2}C{O_3}$ gives $ = \frac{{4 \times 108}}{{2 \times 276}}$
$\therefore $ $2.76\,gm$ of $2A{g_2}C{O_3}$ gives $\frac{{4 \times 108 \times 2.76}}{{2 \times 276}} = 2.16\,gm$
