Hi, I am working on creating rank columns in my data but don't know how. I tried but did it incorrectly and now have to fix it. I have to:

 

# - Rank on the basis of salt concentration

# - Rank on the basis of water permeability coefficient

# - Rank on the basis of solute permeability coefficient

 

Please write code in course hero or as a commenter in the notebook on how to properly do so. The link is below just copy and paste it into google. Use the df dataset. Thanks!
