2. The elemental analysis of an organic solid extracted from gumarabic (a gummy substance used in adhesives, inks, andpharmaceuticals) 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 of0.691 g of the solid in 30.1 g of the solvent diphenyl gave afreezing-point depression of 1.53°C. Calculate the molar mass andmolecular formula of the solid. (Kf for diphenyl is8.00°C/m.)molar mass:___ × 10 ___ g/mol(Enter your answer in scientific notation.)
Molecular Formula:
