Since the membrane has 20 Molecular weight cut-off, that means the molecule with molecular weight higher than 20 will not able to pass. Water molecular weight is 18 so it can pass.

The molecule with molecular weight higher than 20 would be

Protein or amino acid

Urea: molecular weight 60

Na+: molecular weight 23
