1. Calculate the mass of
KHC8H4O4 (molar mass =
204.44g/mol) that reacts with 15mL of NaOH solution in part A.3.
Express this mass of KHC8H4O4 to
the correct number of significant figures and record the
calculation on the report sheet.
2. A 0.204g sample of CO32- antacid is
dissolved with 25.0mL of 0.0981M HCl. The hydrochloric acid that is
not neutralized by the antacid is titrated to a bromophenol
endpoint with 5.83mL OF 0.104M NaOH. Calculate the number of moles...
How many g of MgCl2 (molar mass = 95.21 g/mol) have to be
dissolved to give 100 g of an aqueous solution that boils at 101.50
degree C?
A) 279g
B) 27.9g
C) 95.2g
D) 93.0g
E) 9.30g
