Choccamine and mintanol have Rf values of 0.81 and 0.21 respectively. What would the distance in centimetres (cm) between the two compounds be if the TLC was run on a TLC plate where the solvent front moved 8.9 cm from the baseline?

1. Rf value = (distance by unknown/distance by solvent)
Substitute and solve for distance by the 0.81 material and the 0.21 material, then subtract one from the other to find the distance between them.

We can interpret a distance traveled of 7.43 to mean a distance between 7.425 and 7.435 , thus rounding to 7.43 . Similarly, a time interval of 0.83 implies a time interval between 0.825 and 0.835 . Use these values to justify the
