1.	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.
Answer» Solution :`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`
