Asked by Akashdeep
If a certain oxide of nitrogen weighing 0.11g gives 56 ml of nitrogen and another oxide of nitrogen weighing 0.15 g gives the same volume of nitrogen (both at STP), show that these results support the law of multiple proportions.

22400 ml of N2 = 28 gm so,
56 ml of N2 = 28 x 56/ 22400 = 0.07 gm
Here weight of oxide (A) =0.11 gm
After reduction the weight = 0.07gm
Loss of weight = 0.11-0.07 = 0.04gm (It is the amount of oxygen)--1.
Similarly weight of oxide(B) =0.15 gm
Weight after reduction = 0.07 gm
Hence, in case (A)
0.07 gm of nitrogen combines with 0.04 gm of oxygen
so, weight of nitrogen which would combine with 0.08 gm of oxygen should be equal to
= 0.07 x 0.08/ 0.04 = 0.14 gm--.---2
Here,in both the cases 1 and 2 the weight of nitrogen which combines with fixed amount of oxygen ( 0.04 gm) are 0.07 gm and 0.14 gm which are in the simple ratio of 2:1
Hence the oxides follow the law of multiple proportions.
