Question

The density of sample of adulterated milk is 1032 kg/m^3. while that of pure milk is 1080 kg/m^3. calculate the volume of pure milk in the sample of 10 l given that the density of water is 1000 gm/m3

Answer 1

Density of pure milk = 1080 kg/m3
1080 kg/m3 = 100% pure milk
Density of diluted milk = 1032 kg/m3
1032 kg/m3 = ?
1032 x 100/ 1080
=95.56 
Thus the % o water in milk is 100-95.56 = 4.44%
