Compute the molar mass and molecular formula of the solid

Reference no: EM13253841

The elemental analysis of an organic solid extracted from a gummy substance used in adhesive, ink, and pharmaceutical) showed that it contains 40% C, 6.7% H, and 53.3 % O. A solution of .601g of the solid in 34.1g of the solvent diphenyl gave a freezing point depression of 1.17 degree celsius. Calculate the molar mass and molecular formula of the solid(k1 for diphenyl is 8.00 degree celsius/m)
