Hey, i just need help with the question in the image aboveand also checking to see if I did the calculations correct for Refractive index using the values in the table. Thanks

Section Ill: Purification of a Liquid by Distillation Liquid Observed boiling Observed boiling range (CC) point (EC) Impure Liquid Measured refractive Index Temperature (C) 1. 37 82 22 4 Distillate 11.3609 21.9 Correction of Refractive Index to 20 C (n=nT+0.00045T-20) Result Impure liquid ethanol Cyclohexanol distillate Observed boiling point ( C) Literature boiling point ( 79 141 C) Refractive Index n20 1-379313619 1.3611 1.4641 Is the agreement between your distillate and pure ethanol within experimental error (0.0005 per reading)? What does this tell you about the purity of your distillate
