What amount of hydrogen peroxide should result ( theoretical yield) when 1.50g of barium peroxide is treated with 25.0 mL of hydrochloric acid solution containing 0.0272 g of HCl per mL

Explanation:

Hello!

In this case, for the chemical reaction between hydrochloric acid and barium peroxide is:

Thus, since the barium peroxide (169.33 g/mol) and hydrochloric acid (36.45 g/mol) are reacting in a 1:2 mole ratio, we need to identify the limiting reactant first by computing the yielded moles of hydrogen peroxide by each reactant:

That's why the HCl is the limiting reactant, so the resulting mass of hydrogen peroxide, theoretical yield, is:
