One litre of milk weighs. 1.035 kg. The ...

One litre of milk weighs. `1.035 kg`. The butter fat is `4%(v//v)` of milk has density of `875 kg//m^(3)`. Find the density of fat free skimed milk.

Text Solution

Verified by Experts

The correct Answer is:
`1.041g//mL`
`100mL` milk `rarr 4mL` fat
`1L` milk `rarr 40mL` fat
density of fat `=875kg//m^(3)=0.875g//mL`
mass of fat `=40xx0.875=35g`
fat free milk mass `=1035-35=1000g`
`vol. = 1000-40=960mL`
`p=(1000)/(960)=1.0416g//mL`
