Chapter 2

Explain, in your own words, why samples can often be separated into their components by chromatography.

In this experiment it takes about ten microliters (microliters is abbreviated as \(\mu \mathrm{L}\), and \(1 \mu \mathrm{L}=10^{-6} \mathrm{L}\) ) of solution to produce a spot \(1 \mathrm{cm}\) in diameter. If the \(\mathrm{AgNO}_{3}\) solution contains \(10.8 \mathrm{g} \mathrm{Ag}^{+}\) per liter, how many micrograms of \(\mathrm{Ag}^{+}\) ion are there in one spot? _______ micrograms
