Consider the complete combustion of butane, the amount of butane utilized to produce $72.0 g$ of water is ______ $\times 10^{- 1} g$ . (in nearest integer)

Answer:

464

Solution:

$C_{4} H_{10} + \frac{13}{2} O_{2} ⟶ 4 {CO}_{2} + 5 H_{2} O$

Moles of $H_{2} O = \frac{72}{18} = 4$

Moles of $C_{4} H_{10}$ used $= \frac{1}{5} \times 4$

Weight of $C_{4} H_{10}$ used $= \frac{4}{5} \times 58$

$= 46.4 gm$
