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 ?

Options:

Answer:

Solution:

Molarity of glucose solution $= \frac{0.5 g}{180 \times 1 L} = 0.00277 M$ Isotonic solution have equal molar concentrations, hence molarity of organic compound solution $= 0.00277 M$ $∴$ Molecular weight of compound $= \frac{2.5}{0.00277 \times 1} = 900$
