I'm not completely sure under which category of chemistry this falls under, so here goes

An unknown monobasic acid HA reacts with sodium hydroxide as follows:-

HA + NaOH --->NaA + H2O

Briefly describe a method for determining the molecular weight of the unknown monobasic asid.

Hint - Remember C the concentration of a solution in gdm^-3 and M the molarity (molar concentration) of a solution in moles dm^-3 can be interconverted using the equation:

M = C/(MW)

Where MW is the molecular weight of the substance.


I was thinking along the line of A could be anything, so let's say A = NO3, therefore NaA would be NaNO3, devise an experiment to find the weight of NaNO3 and break it up to find the weight of each specific part, (Na and NO3) and you'll know the monobasic acid..? I'm not really sure if that makes sense because i dont even know how to explain and devise an experiment to find the weight of a substance like NaNO3..any suggestions or help would be appreciated!
