Density is defined as the ratio of mass and volume. The formula of density is:
[tex]density = \frac{mass}{volume}[/tex] -(1)
Density of milk = [tex]1.04 g/mL[/tex] (given)
Volume of milk = [tex]510 mL[/tex] (given)
Substituting the values in formula (1):
[tex]1.04 g/mL = \frac{mass}{510 mL}[/tex]
[tex]mass= 1.04 g/mL \times 510 mL[/tex]
[tex]mass = 530.4 g[/tex]
Hence, the mass of the milk is [tex]530.4 g[/tex].
