An aqueous solution of urea containing 6 g in 500 ml has a density equ – InterviewSolution

1.	An aqueous solution of urea containing 6 g in 500 ml has a density equal to 1.05. If the molar mass of urea is 60, then the molality of the solution is :
Answer» 0.193 M 0.190 M 0.20 M 0.10 M Solution :Mass of solution `=500 ML xx (1.05 "g ml"^(-1))` `=525g` Mass of solvent `=525-6=519g` Urea`=6g=6/60`MOLE MOLALITY `=(6xx1000)/(60xx519)=0.193`m .
