Many home barbeques are fueled with
propane gas (C3H8). What mass of carbon
dioxide is produced upon the complete
combustion of 18.9 L of propane (approximate
contents of one 5-gallon tank)? Assume that
the density of the liquid propane in the tank is
0.621 g/mL.
What volume of 0.500 M Ba(OH)2 will
react completely with 25.0 mL of 0.200 M
HCl?
A 50.0 mL sample of an ammonia solution is
analyzed by titration with HCl. The titration
required 39.47 mL of 0.0984 M HCl to reach
the endpoint. What was the concentration of
the ammonia solution?
A 25.0 mL portion of HCl is titrated with
0.0775 M NaOH. The titration requires exactly
37.46 mL of the standard NaOH solution to
reach the endpoint. What is the molarity of the
HCl solution?
