Question
There is about $1.0 \mathrm{~g}$ of calcium, as $\mathrm{Ca}^{2+}$, in $1.0 \mathrm{~L}$ of milk. What is the molarity of $\mathrm{Ca}^{2+}$ in milk?
Step 1
First, we need to find the molar mass of calcium (Ca). From the periodic table, the molar mass of Ca is approximately 40.08 g/mol. Show more…
