# What volume does 4.68 g H_2O occupy at STP?

Feb 9, 2016

The volume of liquid water at 0 °C is $\text{4.68 mL}$, and the volume of ice at 0 °C is ${\text{5.10 cm}}^{3}$.

#### Explanation:

At 0 °C, water can be a liquid or a solid.

Liquid water at 0 °C

The density of liquid water at 0 °C is $\text{0.9998 g/mL}$.

The volume is given by

4.68 color(red)(cancel(color(black)("g"))) × "1 mL"/(0.9998 color(red)(cancel(color(black)("g")))) = "4.68 mL".

Ice at 0 °C

The density of ice at 0 °C is ${\text{0.9170 g/cm}}^{3}$.

The volume is given by

4.68 color(red)(cancel(color(black)("g"))) × ("1 cm"^3)/(0.9170 color(red)(cancel(color(black)("g")))) = "5.10 cm"^3.
