Suppose now that you wanted to determine the den-sity of a small yellow crystal to confirm that it is sulfur. from the literature, you know that sulfur has a density . of 2.07 g/cm. 3. how would you prepare 20.0 ml of the liquid mixture having that density from pure sam-ples of chcl3and chbr3? (note: 1 ml = 1 cm. 3.)
