Calculate the osmotic pressure of a solution containing 17.1 g of cane - sugar (molecular mass 342) in 500 g of water at 300 K (R = 0.082 lit. atm deg^(-1)mol^(-1)). Density of the solution of urea. Find the molecular weight of urea. |

Answer» `"VOLUME of the solution = Mass/Density"=517.1//1.034cm^(3)=500cm^(3)=0.5L` `pi=(wRT)/(M_(2)V)=(17.1gxx0.082"L atm K"^(-1)"MOL"^(-1)xx300K)/("342 G mol"^(-1)xx0.5L)="2.46 atm."` |
