Question

6. Simplest formula of the compound containing nitrogen (14 gm) for each 40 gm of
oxygen is

Answer 1

Answer:

N205

Explanation:

nitrogen =14/14=1

oxygen =40/16= 2.5

convert it into whole number you will get the answer

Answer 2

Answer: N₂O₅

Explanation:

Molar mass of (N) atom = 14g/mole

Hence,

No of moles of (N) for 14g = $\frac{14g}{14g/mole}$ = 1 mole

Molar mass of (O) atom = 16g/mole

No of moles of (O) for 40g = $\frac{40g}{16g/mole}$ = 2.5 moles

The resultant ratio between N and O = 1 : 2.5 = 2 : 5

That is, the simplest ratio for the No. of moles between N and O = 2 : 5

Therefore, the resultant formula from the given data is : N₂O₅
