It looks like you are trying to determine the density of milk, given its mass when you know its volume, which is 5 cm³. To calculate the density, you can use the formula:
\[ \text{Density} = \frac{\text{Mass}}{\text{Volume}} \]
You'll need the mass of the milk for that volume to find its density expressed in g/cm³. If you provide the mass of the milk in grams, I can help you complete the calculation!
