Metals Density Problem

Stockrool You have a summer internship working in a jewellery laboratory where your job is to explore the properties of some alloys of silver, rhodium and platinum in order to make brighter jewels at a lower cost.

One day, while preparing an alloy, you accidentally left the bottles near the melting furnace and the labels became charred and unreadable. OH NO$!$ You now have three unlabeled bottles of metallic powder. Your task is to design and perform experiments to identify the metals in these bottles.

From a chemical handbook available in your lab, you find that the densities of silver, rhodium and platinum are $10\mathrm{.}5,12\mathrm{.}4$ and $21\mathrm{.}45$ grams per cubic centimeter, respectively. Perform your experiments using the Virtual Lab.

Note: The solution information panel for this activity only displays approximate values for the volume of a substance. Please design your experiment based upon how you would solve this problem in a physical lab. You may find the $10mL$ graduated cylinder, water and scale useful in your measurements. You may also right click on the graduated cylinder and choose 'detail view' to obtain a more precise volume measurement.
