Step-by-step explanation:

To find the density of the mixture, we need to first find the total mass and volume of the mixture.

The mass of 60 cm³ of milk can be found using its density:

mass of milk = volume of milk x density of milk

mass of milk = 60 cm³ x 1.04 g/cm³

mass of milk = 62.4 g

Similarly, the mass of 20 cm³ of water can be found using its density:

mass of water = volume of water x density of water

mass of water = 20 cm³ x 1.0 g/cm³

mass of water = 20 g

The total mass of the mixture is:

total mass = mass of milk + mass of water

total mass = 62.4 g + 20 g

total mass = 82.4 g

The total volume of the mixture is:

total volume = volume of milk + volume of water

total volume = 60 cm³ + 20 cm³

total volume = 80 cm³

The density of the mixture is:

density = total mass/total volume

density = 82.4 g/80 cm³

density = 1.03 g/cm³ (rounded to two decimal places)

Therefore, the density of the mixture is 1.03 g/cm³.
