Range (g/mol) 8,000 16,000 16,000 24,000 24,000 32,000 32,000 40,000 40,000 48,000 48,000 56,000 0.06 0.15 0.24 0.27 0.19 0.09 0.03 0.09 0.18 0.29 0.29 0.12 lick here to access Table 14.3 Atomic weights for several elements are included in the following table Carbon Chlorine 35.45 g/mol 12.01 g/mol Fluo rine 19.00 g/mol Hydrogen 1.008 g/mol Oxygen Nitrogen 14.01 g/mol Compute the following: 16.00 g/mol (a) the number-average molecular weight, g/mol (b) the weight-average molecular weight, g/mol (c) the degree of polymerization.

Explanation / Answer

number average=(12.1+35.45+19+1.008+16+14.01)/6=16.26

weight average

=(12.12+35.452+192+1.0082+162+14.012)/(12.1+35.45+19+1.008+16+14.01)

=22.72

degree of polymerisation=16.26/22.72=0.716
