Furthermore some like brass are actually made up of combinations of other materials as well and depending upon the actual proportions used in their manufacture, the density will vary. Note: brass is made by combining copper and zinc. As the ratio of copper to zinc changes, so does the density of the resulting materialStep by Step Solution
