A proton has about 1836 times the mass of an electron. The best estimate of physicists is that the radius of a proton is about 8×10-16m and the radius of an electron is about 10-16m . If they are correct, then a proton has about ten times the diameter of an electron
Explanation:
The given data is as follows.
Concentration = 3.3 mol
Rate constant = 
Molecular weight = 55000 g/mol

Initial concentration (
) of aminoheptanoic is 3.3 kg/mol.

Hence, putting the given values into the above formula as follows.

= ![\frac{3.3}{2.74 \times 10^{3} kg/mol min} [X_{A}]^{0.1}_{0}](https://tex.z-dn.net/?f=%5Cfrac%7B3.3%7D%7B2.74%20%5Ctimes%2010%5E%7B3%7D%20kg%2Fmol%20min%7D%20%5BX_%7BA%7D%5D%5E%7B0.1%7D_%7B0%7D)
= 120.43 min
Thus, we can conclude that total time required to to form polyamide is 120.43 min.
