Answer #1

The expected weight for the fourth calibration would be the average of the values obtained from the three repetition of calibration.

Thus the expected weight = (1000.03 + 999.96 + 1000.05)/3

= 1000.013 grams

    How would you use separation techniques to recover acetone, 4-carboxyazobenzene, 1-propanol, and cumene in a laboratory experiment. Techniques learned are: Solvent recrystallization, thin layer chromatography, column chromatography, liquid-liquid extraction, distillation. (Would prefer not to do a distillation as this times a long time). Your company has designed a new process to dye rubbers. The process uses cumene to swell the material allowing the organic dye 4-carboxyazobenzene to penetrate more easily. The resulting rubber is able to retain its color, and...
