Explanation / Answer

Ans

1 mol C8H10N4O2 contains hydrogen = 10 mol

2.6 mol C8H10N4O2 contains hydrogen = 2.6 x 10 = 26 mol

1 mol C8H10N4O2 contains nitrogen = 4 mol

0.40 mol C8H10N4O2 contains nitrogen = 0.40 x 4 = 1.6 mol

1 mol C8H10N4O2 contains carbon = 8 mol

2 mol C8H10N4O2 contains carbon = 2 x 8 = 16 mol

1 mol C8H10N4O2 contains oxygen = 2 mol

3.5 mol C8H10N4O2 contains oxygen = 3.5 x 2 = 7 mol
