Question

ypothetical Chromatogram 8 Solvent Front line 7 6 5 3 2 1 Spotting line 0 2) It takes about 3.96(microliters) of a copper solution containing 0.3144 g of copper ion per 100 mL to make a spot approximately 0.3 cm in diame: Calculate the micrograms of copper ion in the e* Using the "ruler" in the picture of the chromatogram and measuring with an accuracy of .1 unit, calculate the retardation factor (Rp) for compound MEASUREMENTS AND CALCULATIONS la) How far did compund C move? b) At the same time, how far did the solvent move? Ic) What is the Rf for compound C? "units". units 2) How many(micrograms) ofcopper ion are in the spo.. Why do la, lb, and 2 have units wheras Ic does not?

Explanation / Answer

Solution:-

1A) Approx 2.5 units

1b) Approx 6.1 Units

1c) Rf= (distance travelled by solute)/(distance travelled by solvent)

= (2.5)/(6.1)

= 0.4098

2) I took the density =0.3144gm/100ml

so microgram of copper ion = (0.3144gm/100ml) * (3.396)microlitre

= 0.010677024 microgram

Note:- 1c) donot have any unit because is defined by (distance travelled by compound )/(distance travelled by solvent) so (mm/mm = dimensionless quantity) that is why it has no units.
