$A$ solution containing $6.0 \ g$ of urea is isotonic with a solution containing $10 \ g$ of a non-electrolytic solute $X$. The molar mass of $X$ (in $g \ mol^{-1}$) is

The solution containing $4.0 \ g$ of a polyvinyl chloride polymer in $1 \ L$ of dioxane was found to have an osmotic pressure of $6.0 \times 10^{-4} \ atm$ at $300 \ K$. Given $R = 0.082 \ L \ atm \ mol^{-1} \ K^{-1}$,the molecular mass of the polymer is:

Calculate the osmotic pressure in pascals exerted by a solution prepared by dissolving $1.0 \ g$ of polymer of molar mass $185,000$ in $450 \ mL$ of water at $37^{\circ} C$.

The empirical formula of a non-electrolyte is $CH_{2}O$. $A$ solution containing $6 \ g$ of the compound exerts the same osmotic pressure as that of $0.05 \ M$ glucose solution at the same temperature. The molecular formula of the compound is
