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.

Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.
