What is the importance of determining the specific gravity using refractometer?

Please help me I am looking forward of a list (3 sources of error and explain it)

Can someone check my question and answers for chromatography lab I m also included data sheet of that lab

A set of experimental data is given below: 19.49, 19.75, 19.66, 19.58, 19.70 a) Determine the mean and the standard deviation. b) Calculate the 95% confidence limit.

please upload the answer properly, don't make an error, so I can see all the answers
