There shouldn't be decimals. Are you multiplying by 1000 after figuring in the percentages?

Then, it's simple math; find the percentage of what you need to add, and add that directly to the beaker. For instance, if you need 11% of acid X and you have 2.2 litres, multiply 2.2 by .11, then multiply that by 1000. Very base; there's no need to calculate dissolution with other acids or anything.
The real difficulty comes in figuring out which acid is in which beaker.

As a reminder: For the acids part, the percentage is the percent of the total volume you need to contribute (ex. 5% * 1.0 L = .05 * 1000mL = 50 ml), and the jars appear to be:
1=hydro, 2=trans, 3=mer, 4=fluor, 5= cyano,
6=pern, 7=zafa, 8=tikio 9=xwee, 10=ox
I haven't confirmed all of the above, but I haven't heard anything definitive about things being wrong either... They don't seem to change between different people, though.
[edit] Don't forget, you must lock it in before time expires for it to be correct.
