What is the molarity of 0.2 N Na₂CO₃solution?

Molarity of solution is related to the normality of the solution as follows, alence factor x Molarity = Normality Let's first calculate the valence factor for 2 3 Na CO The valence factor for a species is equal to the number of moles of electrons gain or lost by the species. In 2 3 Na CO ,there is an exchange of 2 electrons. Therefore, it has 2 as a valence factor. The molarity of 2 3 Na CO is, 2 3 2 3 2 3 Normality Molarity of Na CO = valence factor 0.2 Molarity of Na CO 1 Molarity of Na CO 0.1 M >> Thus,(a) is the correct option. 8.
