WebDebye Equation for the determination of the molecular weight of the solute in solution: 2, 4 0 3 3 32 A c T P n N n H where Debye approach: plot the linear curve of Hc/τE vs. c to obtain intercept (= 1/M) and slope (= 2B). Application of the Debye approach to this work: Measure D at certain λ with various dilution factors (kd). WebThe plot of this is called a Debye. The Molecular weight (M w) was determined from the intercept point on the X axis. i.e. K/CR = 1/M W in Daltons. The 2nd virial coefficient (A 2) was determined from the gradient of the Debye plot (Figure 8).[Citation 48,49] M w and A 2 for each copolymer sample were shown in Table 2.
