What multiple cation problems that equal 72?

To solve for multiple cation problems that equal 72, you can consider combinations of cation charges and quantities. For instance, if you have cations with charges of +1, +2, and +3, you could have a situation where 72 cations of +1 charge contribute 72, or 36 cations of +2 charge contribute 72. Other combinations could include 24 cations of +3 charge, or mixtures of different cation types that sum to 72 when multiplied by their respective charges. The key is to find integer combinations that meet the total of 72.
