Using the provided information in the following paper chromatogram: The calculated R f value of A is _____ × 10 - 1 .

Correct answer

0

Step-by-step solution

R f   =   Distance   travelled   by   compound     Distance   travelled   by   solvent   On chromatogram distance travelled by compound is → 2   cm Distance travelled by solvent = 5   cm So, R f = 2 5 = 4 × 10 - 1 = 0 . 4
