3. Lulu Labwrecker carefully pipets 25.0 mL of 0.525 M NAOH into a test tube. She places the test tube into a small beaker to keep it from spilling and then pipets 75.0 mL of 0.355 M HCI into another test tube. When Lulu reaches to put this test tube of acid into the beaker along with test tube of base she accidentally knocks the test tubes together hard enough to break them and their respective contents combine in the bottom of the beaker. Calculate the number of moles of OH" or H(aq) that completely reacts.

3. Lulu Labwrecker carefully pipets 25.0 mL of 0.525 M NAOH into a test tube. She places the
test tube into a small beaker to keep it from spilling and then pipets 75.0 mL of 0.355 M HCI
into another test tube. When Lulu reaches to put this test tube of acid into the beaker along
with test tube ofbase she accidentally knocks the test tubes together hard enough to break them
and their respective contents combine in the bottom of the beaker. Calculate the number of
moles of OH or H'(aq) that completely reacts.
4. Titration of a 40.0 mL of a 0.150 M HCI solution containing 1.456 g of an antacid tablet
requires 6.00 mL of a 0.300 M solution of NaOH to reach the endpoint. Calculate the grams
of HCI neutralized per gram of antacid tablet.
