100 Chemical Analysis
200 Chemical Analysis
Explain how the empirical
formulas of hydrocarbons are
determined.
300 Chemical Analysis
5.0 g of a mixture containing
some Ag was analyzed to
determine the percent Ag in the
mixture. The mixture was
dissolved in water and excess
NaCl was added. What mass of
AgCl formed if the mixture was
75% silver?
400 Chemical Analysis
7.321 g of an organic compound
containing carbon, hydrogen,
and oxygen was analyzed by
combustion. 17.873 g of carbon
dioxide and 7.316 g of water was
produced. Find the empirical
formula.
500 Chemical Analysis
0.1101 g of a compound containing
C, H, and O was combusted to
produce 0.2503 g CO2 and 0.1025 g
of H2O. The molar mass of the
compound was 115 g/mol. Find
the empirical and molecular
formulas.
100 Molarity
200 Molarity
How would you make 100.0 mL
of a 6 M solution of sodium
chloride in the laboratory?
300 Molarity
50.0 g of sodium hydroxide is
dissolved to make 600 mL of
solution. What is its molarity?
400 Molarity
What is the molarity that
results from adding 25 mL
of a 0.15M solution of
sodium hydroxide to
sufficient water to make 500
mL of solution?
500 Molarity
When excess silver nitrate is added
to a 25.0 mL sample of a solution of
potassium chloride, 0.9256 g of silver
chloride precipitated. What is the
concentration of the potassium
chloride solution?
