Problem 79P

Calculate the mass percent composition of nitrogen in each compound.

(a) $\mathrm{N}_{2} \mathrm{O}$

(b) NO

(c) $\mathrm{NO}_{2}$

(d) $\mathrm{~N}_{2} \mathrm{O}_{5}$

Equation Transcription:

${N}_{2}O$

$N{O}_{2}$

${N}_{2}{O}_{5}$

Text Transcription:

N_2 O

NO_2

N_2 O_5

Answer 1

Step-by-Step Solution:

Step 1 of 4

a) Mass of one mole of ${N}_{2}O$ = molar mass of ${N}_{2}O$

= (14 * 2) + 16

= 44 g

Number of N moles in one ${N}_{2}O$ mole = 2

Mass of one mole of N = molar mass of N =14g

Therefore, mass of N in one mole of ${N}_{2}O$ = 14 * 2 = 28 g

But one mole of ${N}_{2}O$ means 44g of ${N}_{2}O$

Therefore percentage mass of N in ${N}_{2}O$ = (28 g / 44 g) * 100 %

= 63.63 % .
