The vinegar solution you can purchase at the store is about 5% by mass acetic acid. It will be easier for you to assess your results if you convert 5% by mass acetic acid from weight percent to molarity since your experimental results will be in molarity. Show this conversion in your notebook. You will need to approximate the density of the vinegar solution to complete this conversion

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
