277465 Beta-carotene is the most important of the $A$ vitamins. Its molar mass can be determined by measuring the osmotic pressure generated by a given mass of beta-carotene. If $10 \mathrm{~mL}$ of a solution containing $7.68 \mathrm{mg}$ of beta-carotene, has an osmotic pressure of $3.54 \times 10^{-2}$ bar at $25^{0} \mathrm{C}\left(\mathrm{R}=0.083 \mathrm{dm}^{3}\right.$ bar $\left.\mathrm{mol}^{-1} \mathrm{k}^{-1}\right)$, the molar mass of beta-carotene is

1 $109 \mathrm{~g} / \mathrm{mol}$
2 $54 \mathrm{~g} / \mathrm{mol}$
3 $537 \mathrm{~g} / \mathrm{mol}$
4 $768 \mathrm{~g} / \mathrm{mol}$
