A) Slight less than half that of \[N{{H}_{4}}Cl\]
B) Half that of \[N{{H}_{4}}Cl\]
C) Double that of \[N{{H}_{4}}Cl\]
D) Determined by the amount of solid \[N{{H}_{4}}Cl\] in the experiment
Correct Answer: B
Solution :
| [b] \[\frac{\text{Normal}\,\,\text{molecular}\,\,\text{weight}}{\text{experimental}\,\,\text{molecular}\,\,\text{wt}\text{.}}\]= 1 + a |
| \[N{{H}_{4}}Cl\] \[\rightleftharpoons \] \[N{{H}_{3}}+HCl\] |
| \[\because \alpha =1\] \Experimental Molecular wt =\[\frac{\text{nor}\text{.mol}\text{.wt}\text{.}}{2}\] |
