The concentration of solutions can be expressed in number of ways such that Normality, Molarity, Molality, Mole fractions, Strength, `%` by weight, `%` by volume and `%` by strength. The molarity of ionic compound is usually expressed as formality beacuse we use formula weight of ionic compound. Addition of water to a solution changes all these terms, however increase in temperature does not change molality, mole fraction and `%` by weight terms.
Molecular weight of `O_(3)` in the reaction, `2O_(3)hArr3O_(2)` is:
A. `8`
B. `16`
C. `24`
D. `48`
