Answer:
The eluting strength of a solvent is primarily related to how strongly it adsorbs onto the adsorbent and because typical adsorbents are highly polar; thus, eluting strength increases with solvent polarity.
Explanation:
The polarity of a solvent makes it more suitable for elution in a polar adsorbent. Hence the choice of solvents should be in order of increasing rather than decreasing polarity. polarity must increase and not decrease

Answer:
Explanation:1 mole is equal to 1 moles CaCO3, or 100.0869 grams.
10g/ 763g/mol= 0.013moles
21.69mL - 20.70mL = .99mL Fe
7.8 g / .99 mL = 7.9g/mL
