How would you prepare 75 mL of an H2SO4 solution at 20% in weight (density=1.1394 g/mL, richness=227.9 g/L) starting from the commercial H2SO4 solution (98%, density=1.8361 g/mL, richness=1799 g/L)? Please choose among the most appropriate procedure which better describes the preparation of the previous diluted H2SO4 solution:

Question
How would you prepare 75 mL of an H2SO4 solution at 20% in weight (density=1.1394 g/mL, richness=227.9 g/L) starting from the commercial H2SO4 solution (98%, density=1.8361 g/mL, richness=1799 g/L)?
Please choose among the most appropriate procedure which better describes the preparation of the previous diluted H2SO4 solution:
Select one or more:
a. Take the required volume of commercial H2SO4 solution with an adequate pipette, pour it into a graduated flask and add water up to the final volume (75 mL in this case). Homogenize the flask by stirring it gently.
b. Take a beaker and put about 40 mL of distilled water. Then take the required volume of commercial H2SO4 solution with an adequate pipette and pour them over the beaker. Let the solution be warm and pour the mixture into a graduated flask and add water up to the final volume (75 mL in this case). Homogenize the flask by stirring it gently.
c. Take a beaker and put about 40 mL of distilled water. Then take the required volume of commercial H2SO4 solution with an adequate pipette and pour them over the beaker. Let the solution be warm and pour the mixture into a graduated flask. Measure 35 mL of distilled water in a measuring cylinder and add them to the flask. Homogenize the flask by stirring it gently.
