## Question:

You need to make an aqueous solution of {eq}0.191 \ M {/eq} zinc sulphate for an experiment in lab, using a {eq}125 \ mL {/eq} volumetric flask. How much solid zinc sulphate should you add?

## Molarity:

A simple solution is prepared by dissolving a known molar quantity of a solute in a known volume of a liquid solvent. These two parameters give the concentration of the solute in the solution as a molarity. The units are "mol/L" and the molarity value is independent of the solution volume. A known solute molarity combined with a known solution volume in liters tells you the solute molar quantity required for preparation. This molar quantity can be related to certain measurable parameters, such as a mass in grams.
