For polystyrene in benzene, the intrinsic viscosity was determined as a function of molar mass at 25 °C:

M*10-3, g/mol 6970 4240 2530 838 784 676 353 277
[η], dl/g 11.75 8.15 5.54 2.43 2.32 2.07 1.23 1.07
M*10-3, g/mol 63.8 63.1 43.2 16.05 10.43 8.37 3.99
[η], dl/g 0.358 0.356 0.268 0.136 0.106 0.0932 0.0608

Determine the coefficients of the Mark-Houwink equation from these data.
