936_Calculate the retardation factor.jpg

It takes about 1.04 μL, (microliters) of a copper solution containing 0.5421 g of copper ion per 100 mL to make a spot approximately 0.379 cm in diameter. Calculate the micrograms of copper ion in the spot.

Using the "ruler" in the picture of the chromatogram and measuring with an accuracy of .1 unit,

calculate the retardation factor (R_f) for compound D.

MEASUREMENTS AND CALCULATIONS

1a) How far did compund D move? "units".

1b) At the same time, how far did the solvent move? "units".

1c) What is the Rf for compound D?

2) How many pg (micrograms) of copper ion are in the spot?
