Answer:
A) [tex]RF = 0.428[/tex]
B) [tex]RF = 0.857[/tex]
Explanation:
RF value in thin-layer chromatography plate is defined as the ratio of distance moved by the steroid spot (A) to the distance migrated by solvent front(B)
Hence, mathematically
[tex]RF = \frac{A}{B}[/tex] ------Equation (A)
a) Here [tex]A = 6[/tex] cm and [tex]B = 14[/tex]cm
Substituting the given values in above equation, we get -
[tex]= \frac{6}{14} \\= 0.428\\[/tex]
b) Here [tex]A = 12[/tex] cm and [tex]B = 14[/tex]cm
Substituting the given values in above equation, we get -
[tex]= \frac{12}{14} \\= 0.857\\[/tex]
