Why does the vapor pressure of a solution decrease when an ionic compound is added to it? 1) Most solutes have a positive heat of solvation, causing the temperature of the solution to decrease.
2)There are fewer solvent molecules at the surface, so fewer can vaporize and leave the solution.
3) The mole fraction of solvent is higher, causing a lower vapor pressure.

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.
