An oxide of nitrogen is found to contain nitrogen and oxygen combined

1.	An oxide of nitrogen is found to contain nitrogen and oxygen combined together in the ratio of 7: 16 by mass. Derive the formula of the oxide and name it.
Answer» It is given that nitrogen and oxygen are combined together in the ratio of 7:16 by mass. Mass of nitrogen = 14u Mass of oxygen = 16u and mass of O2 = 16× 2 = 32u Hence, we can write 14:32 which is equal to 7:16 Therefore, the formula of the oxide is NO₂ and its name is nitrous dioxide.

Answer»

It is given that nitrogen and oxygen are combined together in the ratio of 7:16 by mass.

Mass of nitrogen = 14u

Mass of oxygen = 16u and mass of O2 = 16× 2 = 32u

Hence, we can write 14:32 which is equal to 7:16

Therefore, the formula of the oxide is NO₂ and its name is nitrous dioxide.
