Container A has 300 mL of 0.150M Na3PO4 and container B has 200 mL of 0.200M Na2CO3 and are mixed together. The two solutions are mixed together to make a larger solution in a larger container C. Calculate the concentration of Na^+, PO4^3-, and CO3^2-, ions in the final solution of container C.
Calculate the total concentration of ions in the final solution.
