To calculate the density of milk, you can use the formula:
\[ \text{Density} = \frac{\text{mass}}{\text{volume}} \]
You've mentioned that the volume is 5 cm³. However, you will need to provide the mass of the milk in grams to calculate its density.
Once you have the mass, you can plug it into the formula. For example, if the mass of the milk is \(x\) grams, then the density would be:
\[ \text{Density} = \frac{x \text{ g}}{5 \text{ cm}^3} \]
Please provide the mass of the milk so that I can calculate the density for you.
