I need help with an alevel chem question please! (concentration)

I dont know if I'm missing something but I need help (and maybe the answer :smile: ) with this question :

Calculate the total concentration of chloride ions present when a 30.0cm3 0.600 moldm-3 solution of NaCl and a 10.0cm3 0.500 moldm-3 solution of FeCl3 are mixed.

much appreciated!

Calculate the moles of chloride ions provided by both and divide by the total volume.
