Conservation of Mass

Mass is always conserved. As Lavoisier’s law states, mass is neither created nor destroyed in chemical reactions (Nature.com, 2012). The data we obtained in the lab corroborates this. Some other examples would be:

(Amrita Olabs, 2011)

As shown by our data, unlike mass volume is not conserved. Especially in the case of gases, that don’t have a constant volume (Lohninger H., 2014).

Molarity is the relationship between the number of moles of solvent in a solution and the weight in Kg.

Molality is the relationship between the number of moles of solvent in a solution and the volume in L.
