Measured relative viscosity of non-Newtonian cellulose nitrate in acetone as a function of concentration and extrapolated to zero shear rate. Below are the results:
s, g/dL 0.015 0.0176 0.0212 0.0264 0.0352 0.0528
ηrel 1.45 1.53 1.67 1.89 2.31 3.41
Find the intrinsic viscosity from these data and calculate the molar mass using the Mark-Houwink coefficients α=0.98, Kmn=2.04*10-5 dl/g.
