Question

how will you check the purity of milk using hydrometer when the given density of milk is 1.04g/cm³​

Answer 1

Explanation:

A lactometer is a specialized hydrometer used measure the relative density and purity of milk. A lactometer has graduations from 1 3 (top-bottom) between the uppermost marking of W representing the density of water and the lowermost marking of M representing the density of pure milk. If the milk is pure the readings will be close to 1 and if the amount of water in the milk increases then the markings will be close to 3. Since the amount of water in milk increases, the density of milk decreases and the level of submergence of the lactometer increases.
