A bottle of carbonated water contains a liquid and vapor in equilibrium. The liquid contains 0.01mol% CO2 and the rest water when the bottle is left in a hot car (95°F). Calculate the pressure and composition (mole fractions) of the gas.

Step 1

Let the ideal mixing of components in liquid and vapor phases, Raoult’s Law is used for the given question and its equation is written below.

Here,

*x _{i}* is the mole fraction of component

*y _{i}* is the mole fraction of component

*P _{i}^{*}* is the vapor pressure of component

*P* is the total pressure of the system.

Step 2

The mole percent of CO_{2} in liquid phase is given as 0.01%. Therefore, the mole fraction of CO_{2} and water in liquid phase will be

Step 3

At 95°F (35°C), the vapor pressure of...
