1.46 g of a biopolymer dissolved in a 100 mL water at 300 K exerted an osmotic pressure of $2.42 \times 10^{-3}$ bar. The molar mass of the biopolymer is $\_\_\_\_$ $\times 10^4 \mathrm{~g} \mathrm{~mol}^{-1}$. (Round off to the Nearest Integer) $\left[\right.$ Use : $\mathrm{R}=0.083 \mathrm{~L}$ bar mol-1 $\left.\mathrm{K}^{-1}\right]$
