To prepare 1000 mL of a 0.2 mol/L solution of Sulfuric acid we will need to dilute 11.12 mL of 96 % H2SO4 to a final volume with deionized (distilled) water.
To prepare 1000 mL of a 0.3 mol/L solution of Sulfuric acid we will need to dilute 16.69 mL of 96 % H2SO4 to a final volume with deionized (distilled) water.
To prepare 1000 mL of a 0.4 mol/L solution of Sulfuric acid we will need to dilute 22.25 mL of 96 % H2SO4 to a final volume with deionized (distilled) water.
To prepare 1000 mL of a 0.5 mol/L solution of Sulfuric acid we will need to dilute 27.81 mL of 96 % H2SO4 to a final volume with deionized (distilled) water.
To prepare 1000 mL of a 0.6 mol/L solution of Sulfuric acid we will need to dilute 33.37 mL of 96 % H2SO4 to a final volume with deionized (distilled) water.
