suppose now that you wanted to determine the density of a small crystal to confirm that it is phosphorus. from the literature, you know that phosphorus has a density of 1.82 . how would you prepare 20.0 ml of the liquid mixture having that density from pure samples of ( = 1.492 g/ml) and ( = 2.890 g/ml)? (note: 1 ml = 1 .)
