A compound contains only c h and o to analyze the compound, Ask an Expert

Academics

A compound contains only C, H, and O. To analyze the compound, you determine its empirical formula by analysis for C and H, and its molar mass by freezing point depression.

(a) What is the empirical formula if a 0.01510 g sample gives 0.01102 g of H2O and 0.04484 g of CO2
on combustion?

(b) If you dissolve 1.000 g of the powder in 100.000 g of camphor, you find that the melting point of the solution is 177.05 EC. Pure camphor melts at 179.75 EC. The kfp for camphor is !40.0 deg/molal. What is the molar mass of the white powder?
