First, you need to convert these concentrations into moles of each compound. You can do this using this equation...\[c_i=\frac{n_i}{V_{sol'n}}\]Try this first.

whats your reason for picking over E. they both have the same 0.20

ci is the concentration of the species ni is the number of moles of the species V is the volume of the solution. Assume 1L.

Bis Na2CO3 it has 2 Na atoms in one molecule hence its concentration would be highest.

well i think we have to decide it with normality isntd??

max. normality is of B

and as far i do we have to mulitply its concn by charge to get normality dats mine reason to pick B
