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 % .
