Density is defined as the ratio of mass and volume. The formula of density is:
-(1)
Density of milk = (given)
Volume of milk = (given)
Substituting the values in formula (1):
Hence, the mass of the milk is .

Answer:
See Below.
Explanation:
Recall that molarity is defined by moles of solute over liters of solution (mol/L).
Therefore, to make 90.0 mL of 2.0 M MgSO₄, we will need:
Convert this amount to grams. The molecular weight of MgSO₄ is 120.38 g/mol:
Therefore, to make the solution, we can add 22 grams of MgSO₄ into a graduated cylinder, then mix and dilute the solution with distilled water until we reach 90.0 mL.
