Today I have a question, how does the density of ethyl acetate compare with that of water. The density of ethyl acetate is often less than that of water. Looking at it, the density of water is about 1 gram per cubic centimeter, and under normal temperature and pressure, the density of ethyl acetate is about 0.902 grams per cubic centimeter. Compared with the two, the weight is obvious. If the two are mixed together, ethyl acetate floats on the water, and the boundary is clear, because of the difference in density. This property is essential in all kinds of experiments and industrial matters, and it is related to the handling of separation, mixing, and other things, which cannot be ignored.
