Question

The percentage of nitrogen in HNO, is

Answer 1

$\huge{\boxed{\mathfrak{\red{ANSWER!}}}}$

The percentage of nitrogen in HNO3 is 22.228%.

Answer 2

Explanation:

Molecular weight of HNO is

1+ 14 + 16 = 31u

=} for 31u of HNO 14g of nitrogen is present.

=} percent composition of Nitrogen =

(given weight)/molecular weight × 100

= (14/31)×100

= 45.16 % ( approximately )

therefore, the percent composition of N in HNO is nearly 45%
