The most common form of nylon (nylon-6) is 63.68% carbon, 12.38% nitrogen, 9.80% hydrogen, and 14.4% oxygen. calculate the empirical formula for nylon-6.

Answers

The empirical  formula  for nylon-6 is calculated as below find the  moles of each element mole =%  composition/  molar mass that is  carbon = 63.68/ 12 = 5.31  moles            nitrogen=12.38/14=0.88  moles            hydrogen= 9.80/1 = 9.8  moles             oxygen = 14.4/16  = 0.9  moles find  the  mole ratio by  dividing  each moles with  smallest  moles ( 0.88 moles)  that is             carbon = 5.31/0.88 =6             Nitrogen =0.88/0.88 = 1            Hydrogen = 9.80/0.88 = 11           oxygen = 0.9/0.88 =1 therefore the empirical  formula = C6NH11O
