Question

The chemical composition of the repeat unit for nylon 6,6 is given by the formula c12h22n2o2. atomic weights for the constituent elements are ac = 12, ah = 1, an = 14, and ao = 16. according to this chemical formula (for nylon 6,6), the percent (by weight) of carbon in nylon 6,6 is most nearly:

Answer 1

Answer: The percent (by weight) of carbon in nylon 6,6 is 63.7 %.

Step-by-step explanation:

Molar mass of
`C_(12)H_(22)N_2O_2`:

`12* 12 u+22* 1 u+2* 14 u+2* 16 u=226 u`

Total mass of carbon atoms =
`12* 12 u=144 u`

`\% \text{of the carbon by weight}=(144 u)/(226 u)* 100=63.71 \%`

The percent (by weight) of carbon in nylon 6,6 is 63.7 %.
