Methanol(CH3OH) is a nonelectrolyte as it is not readily ionized when melted and dissolved, and a poor conductor of electricity when it is in solution.
Nanelectrolyte Contains covalent bonds and typically nonpolar molecules. Methanol doesn't dissolve in water, as the H of the alcohol functional group is not acidic enough so we can't easily separate it from the molecule.
Ammonium Oxalate (NH4) 2c204 is the formula number and has a mass of 124.0959
