Which of the procedures, if either, is more accurate when making a 1/501/50 dilution of a solution? a)Transfer 1 mL1 mL with a pipet into a 50-mL50-mL volumetric flask. b)Both procedures have the same accuracy. c)Transfer 20 mL20 mL with a pipet into a 1-L1-L volumetric flask. How can the accuracy of either procedure be improved? a)Instead of using a 1/501/50 dilution to make the solution, weigh out the material on a balance and transfer it directly to the volumetric flask. b)Use an Erlenmeyer flask instead of a volumetric flask. c)Calibrate each piece of glassware. d)Use a graduated cylinder instead of a pipet for the transfer.
