Answer:
a. 6.57 cm
b. 8.17 cm
c. 0.80
Explanation:
a. The compound moved from where it was first placed, to a spot 7.57 cm from the bottom of the paper, in other words:
- 7.57 cm - 1.00 cm = 6.57 cm
b. A similar method is made for the solvent:
- 9.17 cm - 1.00 cm = 8.17 cm
c. The Rf of the factor is equal to the <u>distance that the compound moved divided by the distance the solvent moved</u>:
