MCQ
Which sample contains the largest number of atoms ?
- A$1\, mg$ of $C_4H_{10}$
- B$1\, mg$ of $N_2$
- C$1\, mg$ of $Na$
- ✓$1\, ml$ of $H_2O$
$1 \mathrm{mg}$ of $N_{2}=\frac{2 N \times 10^{-3}}{28}$ atoms
$1 \mathrm{mg}$ of $N a=\frac{N \times 10^{-3}}{23}$ atoms
$1 \mathrm{mL}=1 \mathrm{g} H_{2} O=\frac{3 N}{18}$ atoms
