Answer: The vapor pressure of a solution in which the mole fraction of the solute is 0.200 is 80.0 torr
Explanation:
As the relative lowering of vapor pressure is directly proportional to the amount of dissolved solute.
The formula for relative lowering of vapor pressure will be,
where,
= vapor pressure of pure solvent = 100.0 torr
= vapor pressure of solution = ?
i = Van'T Hoff factor = 1 for nonvolatile, nonelectrolyte solute
= mole fraction of solute = 0.200
The vapor pressure of a solution in which the mole fraction of the solute is 0.200 is 80.0 torr
Answer:
Follows are the solution to the given points:
Explanation:
In point a:
Just the y-axis graph intensity as well as the "y" absorption. Find a path or intercept utilizing Excel or simple math.
In point b:
There are two different ways:
Graphically = Then add the unknown absorbance.
Its intensity of the unknown, if they consider the y axis to pull the straight line to the line marked but instead drop it off on the x-axis.
= resolve, from of the line even for the x variable and also get on
Plug and the un-concentration is also in place
