Question #20808

If 5 grams of nitrogen is oxidized in air, then what is the empirical formula of compound, if it's mass is 19.3 grams?

Expert's answer

General equation for this process is next:

N

let's find x

5 19.3

N

28 2(14+16x)

2(14 + 16x)*5 = 28* 19.3

2(14 + 16x)*5 = 540.4

14 + 16x = 54.04

16x = 40

x = 2.5

so empiric formula is NO

N

_{2}+ xO_{2}= 2NO_{x}let's find x

5 19.3

N

_{2}+ xO_{2}= 2NO_{x}28 2(14+16x)

2(14 + 16x)*5 = 28* 19.3

2(14 + 16x)*5 = 540.4

14 + 16x = 54.04

16x = 40

x = 2.5

so empiric formula is NO
