Could someone explain to me how to solve this?(adsbygoogle = window.adsbygoogle || []).push({});

I have a 10 gallon solution made up of 6.40%Cl, 5.52%Na, and 4.11%Ca, with a density of 1.21. How much HCl is needed to get the %Cl up to a 6.60%, and what would the theoretical %Na and %Ca be after the HCl addition?

Can anyone show me the steps to solve this?
