Less than $1\%$ of $22.4 	ext{ L}$

Vedclass · Answer

(A) At $STP$,$1 	ext{ mole}$ of water vapor occupies $22.4 	ext{ L}$ of volume,which includes the space between molecules.The actual volume occupied by the molecules is the volume of $1 	ext{ mole}$ of liquid water $(18 	ext{ g})$.Given the density of water is $1 	ext{ g mL}^{-1}$,the volume of $18 	ext{ g}$ of water is $18 	ext{ mL}$ $(0.018 	ext{ L})$.Comparing this to $22.4 	ext{ L}$:$	ext{Percentage} = (0.018 / 22.4) 	imes 100 \approx 0.08\%$.Thus,the actual volume is less than $1\%$ of $22.4 	ext{ L}$.

What is the actual volume occupied by molecules in $1 \text{ mole}$ of water vapor at $STP$?
