I'm not at school but I'm sure this is a school level and I want to show someone I learned to do it properly.

If I wanted to say there was 1mg of NaCL for every 1ml of Toluene in a solution, would it be correct to write on the label like this or some other way:

"%0.1 w/v NaCl in C6H5-CH3"

Thank you for your helpfulness

Why C6H5-CH3 and not toluene?

Other than that - OK.
