I'm given a sample of chemical containing:
- 0.51 g sucrose
- 0.67 g sand
- 0. 43 g sodium carbonate
- 0.34 g rice grains


How can I determine whether this sample matches another unknown sample? What type of tests can I perform on the unknown sample?



Your help would be appreciated.

What parts of the sample are very soluble? Somewhat soluble? What has the highest density? Rice grains are big or small?
