Answer:

0.228 L is the volume that the gas occupies after it is driedand stored at STP.

Explanation:

Pressure of the wet gas = $P=695 Torr=\frac{695}{760}atm=0.914 atm$

1 atm = 760 Torr

Pressure of water vapor = p = 0.0372 atm

Pressure of gas = $P_1=P-p=0.914 atm-0.0372 atm = 0.8768 atm$

Volume of wet gas = $V_1=287 mL=0.287 L$

1 mL = 0.001 L

Temperature of the wet gas = $T_1=28.0^oC=28.0+273 K=301 K$

Pressure of dry gas at STP = $P_2=1 atm$

Temperature of the dry gas at STP , $T_2= 273 K$

Volume of dry gas at STP = $V_2$

Using combined gas law:

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

$\frac{0.8768 atm\times 0.287 L}{301 K}=\frac{1 atm\times V_2}{273 K}$

$V_2=0.228 L =228 mL$

0.228 L is the volume that the gas occupies after it is driedand stored at STP.
