Question

the vapour pressure lowering caused by the addition of 100 g of sucrose to 1000 g of water if the vapor pressure of pure water at 25 ° c (molecular mass 342) ​

Answer 1

The vapour pressure lowering caused by addition of 100 g of sucrose (molecular mass = 342) to 1000 g of wate,if the vapour pressure of pure water at 25∘C is 23.8mm Hg,is. ΔP=23.8×0.29255.792=0.125 mm Hg.
