A 0.5 ~g / L solution of glucose is found to be isotonic with a 2.5 ~g / L solution of an organic compound. What will be the molecular weight of that organic compound ?

Step-by-step solution

Molarity of glucose solution = 0.5 ~g 180 1 ~L =0.00277 M Isotonic solution have equal molar concentrations, hence molarity of organic compound solution =0.00277 M Molecular weight of compound = 2.5 0.00277 1 =900
