Hi,

What is the concentration of Li if there is 200mL of Li_{2}SO_{3} solution?

Here is my attempt:

First,I converted 200mL to 0.2L.

Then I calculated the Li concentration to be (1.5M)(2) = 3.0M.

Should I now multiply the 3.0M by 0.2L? Does the 0.2L even need to be considered?

Not sure what to do next.

All help is very much appreciated! Thanks!
