There is about 1.0 g of calcium as Ca2+ in 1.0 L of milk. What is the molarity of Ca2+ in milk?
meriva

Explanation:

It is known that molarity is the number of moles present in a liter of solution.

           Molarity = \frac{\text{no. of moles}}{volume}

Also, number of moles equal mass divided by molar mass. And, molar mass of calcium is 40.07 g/mol.

               No. of moles = \frac{mass}{\text{molar mass}}

                                     = \frac{1.0 g}{40.07 g/mol}

                                     = 0.025 mol

Therefore, calculate the molarity as follows.

             Molarity = \frac{\text{no. of moles}}{volume}

                            = \frac{0.025 mol}{1.0 L}  

                            = 0.025 M

Thus, we can conclude that molarity of Ca^{2+} in milk is 0.025 M.
