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

Accepted Solution
Step-by-Step Solution:

Step 1 of 4

a)  Mass of one mole of  = molar mass of  

= (14 * 2) + 16

= 44 g

Number of N moles in one  mole = 2

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

Therefore, mass of N in one mole of  = 14 * 2 = 28 g

But one mole of  means 44g of  

Therefore percentage mass of N in  = (28 g / 44 g) * 100 %

= 63.63 % .
