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 % .
