MCQ
The weight of a molecule of the compound ${C_{60}}{H_{122}}$ is
- ✓$1.4 \times {10^{ - 21}}$ $g$
- B$1.09 \times {10^{ - 21}}$ $g$
- C$5.025 \times {10^{23}}$ $g$
- D$16.023 \times {10^{23}}$ $g$
$\therefore $ $1$ molecule ${C_{60}}{H_{122}}$ has mass $\frac{{842}}{{6 \times {{10}^{23}}}}$
$ = 140.333 \times {10^{ - 23}}gm$ $ = 1.4 \times {10^{ - 21}}\,gm$.
