A solution of an organic compound is preaped by dissolving 68.4 g in 1000 g of water .Calculate pressure of the solution at 293 K when elevation in boiling point is 0.104 and `K_(b)` for water is `0.53 Km^(-1)` .

Answer

`342,4.80 atm`

Explanation

`M_(B) = (0.52 xx 68.4 xx 1000)/(0.104 xx 500) = 342`
` pi = (68.4 xx 0.082 xx 293)/(342 xx 500) = (V = 1000 g =1 L)`
` = 4.80` atm.
