Problem 15.40

(a) How much ethylene glycol must be added to 20.0 kg of dimethyl terephthalate to produce a linear chain structure of poly(ethylene terephthalate) according to Equations 15.9? (b) What is the mass of the resulting polymer?

Step-by-Step Solution:
Step 1 of 3

AFTER MIDTERM 2 3RD last week 3D plotting Create matrices for X and Y like this: ​ [X,Y] = meshgrid(­10:.5:10); The variables are then available to use in equations: R = sqrt(X.^2+Y.^2); Z = sin(R)./R; The “n” in the syntax for contour are for how many lines there are in a side view Command Window: >> [X,Y] = meshgrid(­10:.5:10); >> R = sqrt(X.^2+Y.^2); >> Z = sin(R)./R; >> surf(Z) Curve Fitting Calculate the line of best fit for the points: ​ (5,9) (4,7) (3,5) (2,4) (1,2) Data To Fit
