Given information
The vapor pressure at is .
Step-by-step explanation
Step 1.
The vapor pressure of pure water at is .
The vapor pressure of an aqueous solution is calculated by the formula,
Where,
-
is the mole fraction of water.
-
is the vapor pressure of pure water.
Rearrange the above formula to calculate the mole fraction of water.
Substitute the value of vapor pressure of pure water and vapor pressure at in the above formula.
The mole fraction of water is .
The total mole of solution is assumed to be .
Hence, the number of moles of water in solution is .
