CALCULATIONS 
A. Calculation of Rf value of glycine: 
R_{f} = distance travelled by glycine from application point
distance travelled by solvent from application point



R_{f} = 
/ 
B. Calculation of Rf value for valine: 
R_{f} = distance travelled by valine from application point
distance travelled by solvent from application point



R_{f} = 
/ 
RESULT 
1. Rf value of glycine = 
2. Rf value of valine =
