**Accepted 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 % .
