On complete combustion 0 . 30 g of an organic compound gave 0 . 20 g of carbon dioxide and 0 . 10 g of water. The percentage of carbon in the given organic compound is____(Nearest Integer)

Correct answer

0

Step-by-step solution

C x H y O z + x + y 4 - z 2 O 2 → xCO 2 + y 2 H 2 O 0 . 3   g                                                                           0 . 2   g             0 . 1   g CO 2 n H 2 O n = x y 2 = 0 . 2 44 0 . 1 18 = 9 11 x = 9 y 22 Now, C x H y O 2 n CO 2 n = 1 x ⇒ 0 . 3 12 x + y
