Consider the complete combustion of butane, the amount of butane utilized to produce 72 . 0 g of water is ______ × 10 - 1 g . (in nearest integer)

Correct answer

0

Step-by-step solution

C 4 H 10 + 13 2 O 2 ⟶ 4 CO 2 + 5 H 2 O Moles of H 2 O = 72 18 = 4 Moles of C 4 H 10 used = 1 5 × 4 Weight of C 4 H 10 used = 4 5 × 58 = 46 . 4   gm
