Chapter 7 Section 5 in your lecture textbook covers the calculations needed for this
week's lab. They are very similar to calculations we covered previously. Complete the
following before coming to lab. It will be GRADED!
Given the balanced equation:
HBr(aq) + NaOH(aq) →
NaBr(ag) + 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
(0.256 MBr)(l00 mb) :25.0 mmoles of HBr
(b) Calculate the number of mmoles of NaOH in 100.0 mL of 0.250 MNAOH
(100 mL) (1.25O MN. PH) =25.0 mmoles of NAOH)
(c) 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.

(d) Using the mmoles of salt produced and the total volume in ml of solution (from the
mixing of the acid and base solutions), calculate the molarity of the salt solution
produced by this reaction.
