Question

hii frnds .... tell me how to calculate Vapor pressure...what is its formula ?

Answer 1

Psolution = the vapor pressure of the solution

solvent = the mole fraction of the solvent in the solution

P°solvent = the vapor pressure of the pure solvent at standard conditions

Answer 2

write raoults law
1 identify the solvent and solute in your solution
2 find the temperature
3 find the sovents vapour pressure
4 find the mole fraction of your solvent
6 solve
