Question
Chapter 19, Problem 19.65QP
Interpretation Introduction
Interpretation:
Reason for strontium-90 particularly dangerous isotope for humans has to be explained.
Concept Introduction:
Isotopes are atoms having same
Radioactive isotopes are atoms that contain an unstable nucleus and dissipate excess energy by spontaneously emitting radiation in the form of alpha, beta, gamma rays.
Strontium-90 is limited in use because of its calcium like property.

Propagation of uncertainty. You have a stock solution certified by the manufacturer to contain 150.0±0.03 µg SO42-/mL. You would like to dilute it by a factor of 100 to obtain 1.500 µg/mL. Calculate the uncertainty in the two methods of dilution below. Use the following uncertainty values for glassware:
Glassware
Uncertainty

1.00 mL volumetric pipet
0.01 mL
10.00 mL volumetric pipet
0.02 mL
100.00 mL volumetric flask
0.08 mL
Transfer 10.00 mL with a volumetric pipet and dilute it to 100 mL with a volumetric flask. Then take 10.00 mL of the resulting solution and dilute it a second time with a 100 mL flask.
2. Transfer 1.00 mL with a volumetric pipet and dilute it to 100 mL with a volumetric flask.
