I'm really stumped on this question, : (
suppose now that you wanted to determine the density of a small crystal to confirm that it is graphite. from the literature, you know that graphite has a density of 2.25 g/cm^3 . how would you prepare 20.0 ml of the liquid mixture having that density from pure samples of chcl^3 ( d = 1.492 g/ml) and chbr^3 ( d = 2.890 g/ml)? (note: 1 ml = 1 cm^3.)
