When 31 g of non-volatile solute is dissovled in 100 g of water, the v – InterviewSolution

1.	When 31 g of non-volatile solute is dissovled in 100 g of water, the vapour pressure is lowered by 1.75 mm. If the vapour pressure of water at 25 oC is 17.5 mm, what is the molecular mass of solute ( in g)?(Use 10018=5.55)
Answer» When $31 g$ of non-volatile solute is dissovled in $100 g$ of water, the vapour pressure is lowered by $1.75 mm$ . If the vapour pressure of water at $25^{o} C$ is $17.5 mm$ , what is the molecular mass of solute $(in g)$ ? (Use $\frac{100}{18} = 5.55$ )
