Given the balanced equation: HBr(aq) + NaOH(aq) NaBr(aq) + H2O) and remembering that Molarity = moles/liter OR mmoles/mL (1) (a) Calculate the number of mmoles of HBr in 100.0 mL of 0.250 MHBR (b) Calculate the number of mmoles of NaOH in 100.0 mL of 0.250 MNAOH © When these two solutions are mixed the acid and base should neutralize one another exactly. This means that all of the acid and base are completely used up; either one could be considered a "limiting reactant". Starting with the mmoles of either the acid or base, calculate the number of mmoles of salt produced by the reaction.
