InterviewSolution

1.	A 5% solution of cane sugar (molar mass = 342) is isotonic with 1% solution os a substance X. The molar mass of X is:
Answer» 171.2 68.4 34.2 136.2 Solution :`pi=(W_(B)xxRxxT)/(M_(B)XXV)` R, T and V are constants for ISOTONIC SOLUTIONS `pi_(x)=pi_(sugar)1/M_(x)=5/342` `or M_(X)=342/5=68.4`
