4.00 ml оf 0.50 M HBr reаcts with 16.00 mL оf 0.50 M Bа(OH)2 in а stоichiometry study using the methods of continuous variations. The stoichiometry of the system was shown by the following balanced equation: Ba(OH)2(aq) + 2HBr(aq) → BaBr2(aq) + 2H2O(l) On the basis of the limiting reagent, calculate the theoretical number of moles of product (BaBr2) that should have been formed.
