Sorbitol is a sweet substance founding fruits and berries as well as sometimes used as a sugar substitute. If an aqueous solution containing 1.00 gram sorbitolin 100.0 grams water is found to have a freezing point of -0.102°C. Elemental analysis indicates that sorbitol consists of 39.56% C, 7.75% H, and 52.70% O by mass. Explain what is the (a) molar mass and (b) molecular formula of sorbitol?
