Explanation:
It is known that molarity is the number of moles present in a liter of solution.
Molarity =
Also, number of moles equal mass divided by molar mass. And, molar mass of calcium is 40.07 g/mol.
No. of moles =
=
= 0.025 mol
Therefore, calculate the molarity as follows.
Molarity =
=
= 0.025 M
Thus, we can conclude that molarity of in milk is 0.025 M.
