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).
