http://treinwijzer-a.ns.nl/how+to+determine+molar+mass+of+unknown+acid WebSep 29, 2015 · I am assuming: because at the equivalence point half of the acid has been converted to it's conjugate base and so ( 2 m o l N a O H = 1 m o l H 2 A ). If this is correct then 0.002160 m o l N a O H ⋅ 2 m o l H 2 A / m o l N a O H = 0.004320 m o l H 2 A Which I then divide the g/mol 0.2600 g 0.00432 m o l = 60.19 g / m o l
