The elemental analysis of an organic solid extracted from gum arabic showed that it contained 40.0 % C, 6.7% H, and 53.3% of O. A solution of 0.583g of solid in 27.5g of the solvent diphenyl gave a freezing point depression of 1.41'C. Calculate the molar mass and the molecular formula of the solid. (Ki for diphenl is 8.00'C/m)
