A sample of an unknown liquid has a volume of 12.0 mL and a mass of 6 g. What is its density? Show your work or explain how you determined this value.

To calculate the density of a substance, we can use the formula:

\[
\text{Density} = \frac{\text{Mass}}{\text{Volume}}
\]

In this problem, we are given:
- Mass (\( m \)) = 6.0 g
- Volume (\( V \)) = 12.0 mL

Substituting these values into the formula:

\[
\text{Density} = \frac{6.0 \, \text{g}}{12.0 \, \text{mL}} = 0.5 \, \text{g/mL}
\]

**Answer**: The density of the unknown liquid is \( 0.5 \, \text{g/mL} \).
