To a weighed, clean and dry 1.0 L volumetric flask some pure NH4CI is added and the flask is reweighed. Then distilled water is added to dissolve NH4CI and finally enough water is added, with stirring, to bring the solution to the 1 L mark. The flask is reweighed. Data is given below : Mass of clean and dry 1 Lflask:224.3 g. Mass of flask plus NH4CI:274.3 g Mass of flask plus NH4CI plus water:1224.3 g. w/w of NH4CI in solution is X. The value of X is
