## Question:

15 grams of NaCl is dissolved completely in a beaker containing 200 mL of water. What is the Na{eq}^+ {/eq} concentration in moles/liter in the final solution?

## Molarity:

The molarity of a solution is the number of moles per unit volume(usually the liter). When given the mass of the solute, we use the molar mass as a conversion factor to determine the number of moles. After that, the number of moles divided by the volume gives the molar concentration or molarity.
