volume of milk is given as
[tex]V = 2 Gallon[/tex]
we will convert it into mL unit
[tex]V = 2 Gal = 7570.82 ml[/tex]
mass of the milk m = 2kg
m = 2000 g
now for the density we can use
[tex]\rho = \frac{m}{V}[/tex]
[tex]\rho = \frac{2000}{7570.82}[/tex]
[tex]\rho = 0.264 g/mL[/tex]
so the density is 0.264 g/mL for above sample
