Elemental analysis of squalene, a natural and vital part of the synthesis of all plant and animal sterols, shows that it contains 14.37 %% HH and 85.63 %% CC. Dissolving 0.0250 gg of squalene in 1.50 gg of camphor gives a freezing-point depression of 1.53 ∘C∘C.
What is the molecular weight of squalene? [KfKf for camphor is 37.7 (∘C⋅kg)/mol(∘C⋅kg)/mol]. = 411
What is the molecular formula of squalene?

Molecular Formula from Elemental Analysis and Molecular Mass Determination An unidentified covalent molecular compound contains only carbon, hydrogen, and oxygen. When 7.80 mg of this compound is burned, 18.12 mg of CO2 and 1.98 mg of H2O are produced. The freezing point of camphor is lowered by 26.4°C when 3.236 g of the compound is dissolved in 17.25 g of camphor (Kf = 40.0°C kg/mol). What is the molecular formula of the unidentified compound? Choose appropriate coefficients in the molecular...
