If water is added to a 0.70 M solution of CoCl2, what will change?

- Volume of the solution will increase.

- Molarity will decrease.

Explanation:

Hello,

In this case, for molarity, unit of concentration relating the moles of solute and volume of solution, we have:

Hence, since the given molarity is 0.70M, we first shall infer that by adding more water, that for sure is the solvent, the volume of the solution will increase which will be the first change. Moreover, since the volume and the molarity are in an inversely proportional relationship, as the volume increases the molarity decreases, which is the other change. In addition to the aforementioned statements, the moles of the solute are not modified as just water is added.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
