Question

1. What is the total molar concentration of ions in a 0.350 Msolution of the strong electrolyte Na2SO4,assuming complete dissociation? 2. What is the molar concentration of Br- ions in a0.225 M aqueous solution of FeBr3 assuming completedissociation? 1. What is the total molar concentration of ions in a 0.350 Msolution of the strong electrolyte Na2SO4,assuming complete dissociation? 2. What is the molar concentration of Br- ions in a0.225 M aqueous solution of FeBr3 assuming completedissociation?

Explanation / Answer

In the first question there are a total of 3 ions in themolecule. So times the .35 M by three and that is your newmolar concentration. =1.05 M of ions For the second question times the molarity by three againbecause there are three moles of Br- ions in the solution. So theanswer is .675 M of Br-
