The elemental analysis of an organic solid extracted from gum arabic (a gummy substance used in adhesives, inks, and pharmaceuticals) showed that it contained 40.0 percent by mass C, 6.7 percent by mass H, and 53.3 percent by mass O. A solution of 0.719 g of the solid in 33.3 g of the solvent diphenyl gave a freezing-point depression of 1.44C. Calculate the molar mass and molecular formula of the solid. (Kf for diphenyl is 8.00C/m.)
