Q. A bottle of cold drink contains 200 mL liquid in which $CO_{2}$ is 0.1 molar. Suppose $CO_{2}$ behaves like an ideals gas, the volume of the dissolved $CO_{2}$ at STP is

Solution:
Number of mole of $CO_{2}$ in 200 mL solution
$=200\times 10^{- 3}L\times 0.1\frac{m o l}{L}=0.0200$ mol
Since the $CO_{2}$ behaves like an ideal gas therefore, volume of 0.0200 mol of $CO_{2}$ at STP
$=0.0200$ mol $\times \frac{22.4 L C O_{2}}{1 m o l}=0.448$ L.
$=200\times 10^{- 3}L\times 0.1\frac{m o l}{L}=0.0200$ mol
Since the $CO_{2}$ behaves like an ideal gas therefore, volume of 0.0200 mol of $CO_{2}$ at STP
$=0.0200$ mol $\times \frac{22.4 L C O_{2}}{1 m o l}=0.448$ L.
