A student developed a TLC plate by spotting the sample 1 cm from the bottom and allowed the solvent to move up to a point 1 cm from the top. He developed this TLC in 30% ethyl acetate in hexane and got a single spot with Rf value 0.3. If the distance travelled by the solvent front was 8 cm, calculate the distance travelled by the spot. Also, calculate the length of the TLC plate he used to do this...
