If a small amount of solid was diluted with a large amount of water, what is the approximate density of the solution?
| It is impossible to know since we don't know the solvent |
| The quantity of solid per mL of solvent |
| at least 2 g/mL |
| 1 g/mL |

A chemist is brought a small solid figurine. The owner wants to know if it is made of silver but doesn’t want it damaged during the analysis. The chemist decides to determine the density, knowing that silver has a density of 10.5 g/mL. The figurine is put into a graduated cylinder that contains 32.6 mL of water. The reading while the figurine is in the water is 60.1 mL. The mass of the figurine is 240.8 g. Is the figurine...
