450 mg of glucose is dissolved in 100 ~g of solvent. What is the molality of solution?

Options

  1. A0.0025 ~m
  2. B0.025 ~m
  3. C0.25 ~m
  4. D2.5 ~m

Correct answer

B. 0.025 ~m

Step-by-step solution

Molality = moles of solute 1000 weight of solvent (in g) Or = weight of solute 1000 mol. wt of solute weight of solvent (in g) = 450 10⁻³ 1000 180 100 [ Mol. mass of glucose =180]=0.025 ~m
