Question 3 3 pts A student carried out a 1:3 serial dilution starting from a stock solution that had a concentration of 1.0 M. The student obtained 5.00 mL of the stock solution and transferred it to a container. How much deionized water should they add in order to complete the first dilution in the series? O 10.00 mL O 5.00 mL O 1.67 ml O 15.00 mL Question 4 3 pts A student transferred 7.00 mL of acetic acid into a flask and then conducted a titration with sodium hydroxide to determine the molarity of the acetic acid solution. Examine the image below and choose the option that best represents the end point of the titration. Use the information provided to calculate the molarity of the acetic acid solution. Vol. of 0.0980 M NaOH added: I. II. III. IV. 12.30 mL I. II. 12.70 mL III. 13.50 mL IV. 16.60 mL
