In chemical research we often send newly synthesized compounds to commercial laboratories for analysis. these laboratories determine the weight percent of c and h by burning the compound and collecting the evolved co2 and h2o. they determine the molar mass by measuring the osmotic pressure of a solution of the compound. calculate the empirical and molecular formulas of a compound, cxhycr, given the following information: (a) the compound contains 73.94% c and 8.27% h; the remainder is chromium. (b) at 25 °c, the osmotic pressure of a solution containing 5.00 mg of the unknown dissolved in exactly 100 ml of chloroform solution is 3.17 mm hg
