An organic compound gives 0 . 220 g of CO 2 and 0 . 126 g of H 2 O on complete combustion. If the % of carbon is 24 then the % of hydrogen is _ _ _ _ _ _ _ _ _ × 10 – 1 . (Nearest integer)

Correct answer

0

Step-by-step solution

Moles of CO 2 = 0 . 22 44 = 1 200 Then, Mass of C = 0 . 220 44 × 12 = 0 . 06   g % of   C = 0 . 06 W × 100 = 24 (W= Wt.of organic compound) W = 0 . 25 Moles of H 2 O = 0 . 126 18 = 0 . 007 Moles of H = 0 . 007 × 2 = 0 . 014   g % of   Hydrogen = 0 . 014 × 1 W × 100                                                       = 0 . 014 × 1 0
