Is this data correct? I think part C is wrong for the density of solution. I wasn't sure what number to divide by

A. MASS OF FISH WEIGHT (Using the Analytical Balance) Unknown If 20 1. Irial Mass of tish weight Mean mass, x=18,2747 standard deviation, s = CYOQ Note that the mean and the standard deviation should have the same number of decimal places. B.
