Answer : The density of the sample in grams per cubic centimeter is, 90g/cm^3

Solution : Given,

Mass of unknown sample = 81 g

Volume of unknown sample = 0.9cm^3

Formula used :

\text{Density of unknown sample}=\frac{\text{Mass of unknown sample}}{\text{Volume of unknown sample}}

Now put all the given values in this formula, we get the density of unknown sample.

\text{Density of unknown sample}=\frac{81g}{0.9cm^3}=90g/cm^3

Therefore, the density of the sample in grams per cubic centimeter is, 90g/cm^3
