The iodide is quantitatively converted to chloride when it is heated in a stream of chlorine. `XI_(3) + 3Cl_(2) rarr XCl_(3) + I_(2)` It 1 gm of `XI_(3)` is converted into `(1)/(3) gm` of `XCl_(3)` then atomic mass of X is :A. `30.75 gm`B. `20.5 gm`C. `61.5 gm`D. `10.25 gm` |

Answer» Correct Answer - A `{:(2XI_(3),+,3Cl_(2),rarr,2XCl_(3),+,3I_(2),),(1 gm,,,,(1)/(3) gm,,,):}` Let atomic mass of X be M `n_(XI_(3)) = n_(XCl_(3))` `(1)/(M + 381) = ((1)/(3))/(M + 106.5)` `M + 106.5 = (M)/(3) + 127` `(2M)/(3) = 20.5` `M = 30.75 gm` |
