Hi Amit,

Given terms

total glycerin content in the solution = 10.2 g/l

glucose solution = 2%

Since, both are isotonic then

pie glycerin = pie glucose (osmotic pressure same)

C1RT = C2RT

C1=C2 (Since, RT cancelled out)

10.2 / Mw X 1 = 2 X 1000 / 100 X 180

Mw = 10.2 X 100 X 180 / 2000

Glycerin molecular weight = 91.8g
