It took 22.97mL of a 0.1174 M NaOH solution to titrate 35.00mL of an HCl solution to its endpoint. Compute the concentration of the HCl solution.
The mixture is 20% benzene by volume. A densitometer gives the density of the mixed stream to be 1.1 g/mL. What are the mass fractions of all three species?
A solution of potassium hydroxide of unkown concentration is used to titrate 15.0 mL of a 2.5M sulfuric acid solution. The volume of the base is needed 27.2mL. What is the molarity of the base?
Dry the hydrate as instructed in the lab procedure, noting down it's mass until it appears to no longer decrease (no more water bound in the sample).
a a 0.2527-g sample of a mixture of mgoh2 and aloh3 was treated with 50.00 ml of 0.225 mol l?1 hclaq. the resulting
