A 5% solution of glucose ( molar mass =180 ) is isotonic with a 2.5% s – InterviewSolution

1.	A 5% solution of glucose ( molar mass =180 ) is isotonic with a 2.5% solution of a substance X at the same temperature. The molar mass of X is :
Answer» 90 45 180 360 SOLUTION :The two solution will have same OSMOTIC PRESSURE so that `(5)/(180)RT=(2.5)/(M) RT` or `M=(2.5)/(5)xx180=90`
