(a) Which will have the highest concentration of potassium ions: 0.20 M KCl, 0.15 M K₂CrO₄, or 0.080 M K₃PO₄?

Hey everyone, we're asked to identify the solution with the highest roaming ions. Starting off with 0.13 molar of our sodium bromide. We can see that we have a 1-1 molar ratio between our sodium bromide and our roaming ions. So when we calculate this out, we end up with a total of 0.13 Moeller roaming ions. Next looking at our 0.10 moller of our calcium bromide, We can see that per one mole of calcium bromide. We have to mole of our bruning ions. And when we calculate this out, we end up with a total of 0.20 molar of our browning ions. Lastly looking at 0.8 moller of our scandia bromide, We see that per one mole of scandia and bromide, We have three moles of ARB roaming ion. And when we calculate this out, we end up with a total of 0.24 molar of our bruning ions. And since we need to identify the solution with the highest roaming ions, Our answer here is going to be our scandia and bromide. Since we ended up with 0.24 moller of our browning ion. So I hope that made sense. And let us know if you have any questions
