3 A solution containing 10g per dm3 of Urea is isotonic with 5% of
a nonvolatile solute calculate gram molecular weight of non
volatile solute

Dear Student,

The computation are expressed below,

moles of urea = 10 g60 gmol=0
167 molconcentration of urea = 0
167 mol 1 lt=0
167 Mby taking basis as 1000 ml 5% = 50 gm per ltmoles of unknown solute = 50m molconcentration of unknown solution = 50m molLnow by computing known and unknown we get,0
167 = 50mm = 299
401 gmol   (molar mass)
