1.575 gm of an organic acid was dissolved in 250 ml of water Further, 20 ml of this solution required 16 ml of `(N)/(8)` alkali solution for complete neutralisation. If the basicity of the acid is 2, find its molecular mass. |

Answer» 16 ml `(N)/(8)` alkali solution `=20ml` of acid solution 2 ml 2 N alkali solution `=20ml` of acid solution `(2xx250)/(20)ml1N` alkali solution `=`250 ml of acid solution 25 ml 1 N alkali solution `=1.575 gm ` acid 1000 ml 1 N alkali solution `=(1.575)/(25)xx1000gm` acid equivalent mass fo the acid `=63gm acid` molecular mass of the acid `=63xx2=126` |
