We have to calculate the density of the given liquid using the provided data.

**Density** of a substance is defined as the *mass contained in unit volume*.

$\overline{){\mathbf{Density}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}\frac{\mathbf{mass}}{\mathbf{volume}}}$

A flask containing 15.0 mL of a liquid weighs 128.1 g with the liquid in the flask and 120.1 g when empty.

Calculate the density of the liquid in g/mL to the correct number of significant digits.
