A solution containing $\displaystyle 15$ g urea (molar mass $\displaystyle =60 \mathrm{~g} \mathrm{~mol}^{-1}$ ) per litre of solution in water has the same osmotic pressure (isotonic) as a solution of glucose (molar mass $\displaystyle =180 \mathrm{~g} \mathrm{~mol}^{-1}$ ) in water. Calculate the mass of glucose present in one litre of its solution.
