Typically the solvent used for the chromatography is rather volatile. So, its likely that the entire solvent will evaporate prior to the completion of the chromatography if the container isn't covered.
Answer:
8.65x10 7 grams of nacl
Explanation:
There are 6.02x10 23 atoms per one mol
so
8.88x 10 29 x (1/6.02 x 10 23)
Will give us mols of NaCl
to go from mols to grams we multiple mols by molar mass
so
1.48x10 6 mols of Nacl x 58.44 g/mol = 8.65x10 7 grams of nacl which can be converted to
86500 kg
