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 .)
