1.	At `25^(@)C` molar conductance of `0.1` molar aqueous solution of ammonium hydroxide is `9.54 ohm^(-1) cm^(2) mol^(-1)` and at infinte dilution its molar conductance is `238 ohm^(-1) cm^(2) mol^(-1)` The degree of ionisation of ammonium hydroxide at the same concentration and termperature isA. `40.800%`B. `2.08o%`C. `20.800%`D. `4.008%`
Answer» Correct Answer - D `%alpha=(lamda^(c))/(lamda^(oo))xx100=(9.54)/(238)xx100=4.008%`
