241. When determining the content of pyrrolidine in water, the following refractive indices of standard solutions were obtained:

Pyrrolidine content, % 6 5 4 3 2 1 0
n 1.4743 1.4552 1.4361 1.4166 1.3783 1.3592 1.3322

Build a calibration curve and determine the percentage of pyrrolidine at n = 1.4426.
