To find the density of milk, we can use the formula for density:
\[ \text{Density} = \frac{\text{Mass}}{\text{Volume}} \]
From the table, the mass of milk is 5.15 g and the volume is 5 cm³.
Now, substituting the values into the formula:
\[ \text{Density of milk} = \frac{5.15 , \text{g}}{5 , \text{cm}^3} = 1.03 , \text{g/cm}^3 \]
Therefore, the density of milk is 1.03 g/cm³.
