Concentration and Dilution Practice Problems
- Calculate the concentration (mol/L) of a solution that contains 10g of HCL in 100mL of
solution.
- A solution contains 0.1 mol HC2H3O2 dissolved in 0.5 L of solution. Calculate the
concentration (mol/L) of the solution.
- 500 mL of a solution contains 0.1 mol HC2H3O2. Calculate the concentration of the solution
if it is diluted with water to the 1 L mark.
- How many moles of acetic acid are required to make 125 mL of a 0.5 mol/L solution?
- Give directions for preparing 2.0 L of 0.250 mol/L HCl using 11.7 mol/L Hcl.
- A 300mL solution containing 23g of NaCl is mixed with a 500 mL solution containing 15g of
Na2SO4. Assuming the solutions are additive determine the concentrations of each of the 3
ions (chloride, sodium and sulphate).
