Beta carotene is the most significant of the A vitamins. Its molarmass (g/mol) can be determined by measuring the osmotic pressure generated by a given mass of beta carotene dissolved in the solvent chloroform. Compute the molar mass of beta carotene if 10.0ml of a solution containing 7.68mg of beta carotene has an osmotic pressure of 26.57mmHg at 25.0C.
