(C) The molar mass of water $(H_2O)$ is $18 	ext{ g/mol}$.The mass of one molecule of water is calculated as $\frac{18 	ext{ g/mol}}{6.022 	imes 10^{23} 	ext{ molecules/mol}} \approx 2.989 	imes 10^{-23} 	ext{ g}$.Given the density of water is $1 	ext{ g/cm}^3$,the volume of one molecule is calculated using the formula $	ext{Volume} = \frac{	ext{Mass}}{	ext{Density}}$.$	ext{Volume} = \frac{2.989 	imes 10^{-23} 	ext{ g}}{1 	ext{ g/cm}^3} \approx 3 	imes 10^{-23} 	ext{ cm}^3$.

One molecule of water has a volume of ........ $\times 10^{-23} \text{ cm}^3$? (Density of water = $1 \text{ g cm}^{-3}$)
