Newly synthesized compounds are often analyzed by burning the compound and collecting the evolved CO2 and H20 (to determine the mass % of C and H), and by measuring the osmotic pressure of the solution of the compound (to determine the molar mass). Calculate the empirical and molecular formulas of a compound, C?H?Cr?, given the following: 1) The compund contains 73.94% C and 8.22% H. The rest is Cr. 2) At 25 degrees celius, the osmotic pressure of a solution containing 5.00 mg of the unknown dissolved in 100 mL of chloroform of 3.17 mm Hg.
