Question

A compound was found to contain nitrogen and oxygen in the ratio 28 g and 80 g respectively. The formula of compound is (A) NO (B) N2O3 (C) N2O5 (D) N2O4

Tardigrade Admin · Accepted Answer

No.of nitrogen atoms = (Mass in grams/Atomic wt.) = (28/14)=2 No of oxygen atoms=(Mass in grams/Atomic wt.)=(80/16)=5 ∴ Formula of compound is N2O5

Q. A compound was found to contain nitrogen and oxygen in the ratio $28 g$ and $80 g$ respectively. The formula of compound is

$NO$

$N_{2} O_{3}$

$N_{2} O_{5}$

$N_{2} O_{4}$

No.of nitrogen atoms $= \frac{M a ss in g r am s}{A t o mi c wt .} = \frac{28}{14} = 2$
No of oxygen atoms $= \frac{M a ss in g r am s}{A t o mi c wt .} = \frac{80}{16} = 5$
$∴$ Formula of compound is $N_{2} O_{5}$
