A 60mL mixture of nitrous oxide and nitric oxide is totally decomposed

1.	A 60mL mixture of nitrous oxide and nitric oxide is totally decomposed. The volume of the mixture after passing through alkaline pyogallol is 48mL. Calculate the weight percentage of the diatomic oxide in the
Answer» Solution :The balanced equations for the DECOMPOSITION of NITROUS oxide `(N_(2)O)` and nitric oxide (NO) are given as `N_(2)O to N_(2)+(1)/(2)O_(2),NOto(1)/(2)N_(2)+(1)/(2)O_(2)` The volume of mixture initially = 60mL Let the volume of `N_(2)O` in the initial mixture =X Volume of `N_(2)O` in the initial mixture =60-x The volume of nitrogen finally =48mL `60-x+(x)/(2)=48` The RATIO of MOLES of NO:NO = ratio of volumes = 24:36 = 2:3 Ratio of weights =2 x 30:3x44=5:11 Weight percentage of No`=(5)/(16)x100=31.25%`
