Homogenized whole milk contains 4% butterfat by volume. how many milliliters of fat are there in a glass (250 ml) of milk?

Volume of one glass of milk = 250 mL

Percent by volume of butterfat in homogenized milk = 4%

This means 4mL butterfat is present per 100mL milk

Volume of fat present in 250 mL of homogenized milk:

Therefore, 250mL homogenized milk which is 4 % butterfat contains 10mL butterfat.

If the density of butterfat is 0.8g/mL, the mass of butterfat present in 250mL milk will be:

clouds form

solid ice forms on leaves.

water droplets form on grass.
