- <em><u>Rubbing alcohol molecules have a polar and nonpolar part, which means they are able to form hydrogen bonds with water and therefore able to mix with it.</u></em>
- Salt is an ionic compound, meaning it is a substance made up of electrically charged molecules called ions. Therefore, because <em><u>table salt ions are charged, they dissolve much better in a polar solvent, which is also slightly more charged than a nonpolar solvent.</u></em>
mass of proton mp=1.672621898e-27 kg and 1 amu=1.66053904e-27kg so it’s just divition (1.672621898e-27 / 1.66053904e-27) =1.007276 amu
