Maple syrup has a density of 1.325 g/ml, and 100.00 g of maple syrup contains 67 mg of calcium in the form of ca2+ ions. what is the molarity of calcium in maple syrup?

Explanation:

As density is mass divided by volume. And, it is given that mass of maple syrup is 100.00 g and its density is 1.325 g/ml.

Hence, volume of this maple syrup will be calculated as follows.

               Volume =

                             =

                             = 75.47 ml

or,                          = 0.07547 L          (as 1 L = 1000 ml)

Also, number of moles =

It is given that mass of calcium present in maple syrup is 67 mg and molar mass of calcium is 40 g/mol.

Hence, calculate the number of moles of ions as follows.

           number of moles =

                                        =        

                                        = 1.675 mol

As molarity is the number of moles present in liter of solution. Hence, calculate the molarity of calcium in maple syrup as follows.

             Molarity =

                           =

                           = 22.19 M

Therefore, we can conclude that molarity of calcium in maple syrup is 22.19 M.
