Question

Given the reaction, N2 + 2O2→ 2NO2, 14 grams of nitrogen gas will yield approximately 46 grams of nitrogen dioxide.

Answer 1

Answer:

N

2

+2O

2

→2NO

2

As per reaction, it is clear that 28 g ( 1 mol ) of N

2

gas produces the 92 g (2 mol ) of NO

2

,

7 g of N

2

=

28

7

=

4

1

=0.25 moles.

Now , 0.25 moles of N

2

will produce the 0.5 moles of NO

2

,

At STP, the molar volume of any gas is 22.4 L.

Hence,

273

1×22.4

=

300

0.9×V

so V = 27.35 L for 1 mol of NO

2

so for 0.5 mol of NO

2

=

2

27.35

=13.7 L
