The elements present are nitrogen, hydrogen, carbon and oxygen. Kevlar, a polymer is used to make bullet proof vests. Chemical analysis gives C=70.57%; H= 4.23%; O=13.43%.
1. Determine the empirical formula for the monomer in the Kevlar?
2. If 1.00 grams of the polymer are dissolved in the 150.0 mL of water at 25.0 deg C, the osmotic pressure is 0.531 torr. An osmotic pressure experiment can be done to determine the molecular weight of the polymer. Determine the molecular weight of the polymer? Determine the numbers of nonnumeric units is that?
