Problem
Two beakers each contain aqueous KBr solutions at the same temperature. Beaker A is described as “twice as concentrated” as Beaker B. A particle diagram for Beaker B shows 4 K⁺ ions and 4 Br⁻ ions. How many K⁺ and Br⁻ ions should be shown for Beaker A if the diagrams for both beakers use the same box volume?
