Question

Hydrogen peroxide can be prepared by the reaction of barium peroxide with sulfuric acid according to
BaO2(s)+ H2SO4(aq)---> BaSO4(s)+ H2O2(aq)

How many milliliters of 3.00 M H2SO4(aq) are needed to react completly with 85.1g of BaO2(s)?

Answer 1

Here is an example of a stoichiometry problem. Just follow the steps. When you get to the end and have moles, remember
M = moles/L of soln.
