BaO2(s) + 2 HCl(aq) H2O2(aq) + BaCl2(aq)

Question

What amount of hydrogen peroxide should result when 1.00 g of barium peroxide is treated with 15 mL of hydrochloric acid solution containing 0.0330 g of HCl per mL?

So confused... >.<

Answer 1

This is a limiting reagent problem Working these boils down to doing two problems within the one and using the smaller value. Here is a set of directions that will do all limiting reagent problems. The only difference in this problem is you aren't given grams HCl directly but it is available indirectly; i.e., 15 mL x g/mL = grams.
