Density is defined as the ratio of a substance's mass to its volume. We can look at it as the amount of mass per unit volume.

The formula for density is:

`d = m/V` where m is mass, and V is volume. Usually, density is expressed in gram per millilitre, or gram per cubic centimer (for solids and liquids) and gram per liter (for gases).

We know that a liquid with mass 10.568 grams occupies 9.50 ml. Hence, its density is:

`d = (10.568 g)/(9.50 ml) = 1.112421053 g/(ml)`

In proper significant figures, the answer should be 1.11 g/ml. (The operation is division, and as such, we use the least number of significant figures -- in this case, that is 3, from the measurement of its volume).

Density is mass/volume. 

`D = m/v`

Low density objects/liquids tend to float, while high density objects/liquids tend to sink. Helium has a very low density. 

`D = 10.568/9.50`

`D = 1.11 "g"/"mL"`

The lowest number of sig figs in the given values is three, so your final answer should also have three sig figs. 

Water's density is 1.0 g/mL, so this liquid would sink when mixed with water.
