List of top Textile Engineering and Fibre Science Questions on Molecular architecture

The molecular weight (M) of a polymer is determined from Mark-Houwink equation by using coefficient \( K = 11.5 \times 10^{-3} \) ml/g and exponent \( a = 0.73 \). If the measured intrinsic viscosity \( [\eta] \) of the solution is \( 6.0 \times 10^2 \) ml/g then the value of \( M \times 10^{-6} \), (rounded off to two decimal places), is \(\underline{\hspace{2cm}}\).
Assuming the atomic mass of H = 1, C = 12, N = 14, and O = 16, the molecular mass of a repeat unit of Nylon 6 fibre is \(\underline{\hspace{2cm}}\).
