Suppose now that you wanted to determine the density of a small crystal to confirm that it is silicon. from the literature, you know that silicon has a density of 2.33 g/cm3 . how would you prepare 20.0 ml of the liquid mixture having that density from pure samples of chcl3 (d = 1.492 g/ml) and chbr3 (d = 2.890 g/ml)? (note: 1 ml = 1 cm3 .)
