If I'm given 0.025 molar solution of Li2SO4(aq) and I have to find the concentration of each ion, how would I go about doing it? THANKS!

My work (just li): 0.025M Li2SO4*(2MolLi/1MolLi2SO4)=.....Would that be right? I feel like there has to be one more step...How should I set this up for Lithium?

well, lithium sulfate is ionized, so the conc of lithium must be twice the solute concentration, and the sulfate must be the same as the solute conc. Yes, you did it correct, and you set it up for lithium.
