A mixture is prepared by adding 50.0 mL of
0.220 M potassium bromide to 50.0 mL of
0.280 M lead (II) nitrate. What mass of
precipitate can be formed? What is the
concentration of all ions remaining in the
solution?
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.
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?
