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 (integer)
464
Solution
$${C_4}{H_{10}} + {{13} \over 2}{O_2}\buildrel {} \over
\longrightarrow 4C{O_2} + 5{H_2}O$$<br><br>Moles of ${H_2}O = {{72} \over {18}} = 4$<br><br>Moles of C<sub>4</sub>H<sub>10</sub> used $= {1 \over 5} \times 4$<br><br>Wight of C<sub>4</sub>H<sub>10</sub> used $= {4 \over 5} \times 58$<br><br>= 46.4 gm = 464 $\times$ 10<sup>-1</sup> g
