Density Column Post Lab Assessment

Suppose the densities of your solutions were measured as follows:
No sugar - 0.991 g/mL

2 sugar - 1.05 g/mL

4 sugar - 1.20 g/mL

The density of a plastic bottle cap is approximately 0.92 g/mL.  Where would this fall in your density column?

• All the way at the bottom.

• Between the 2 sugar and 4 sugar layer.

• Between the no sugar and 2 sugar layer.

• It would float on top.
