For the following reaction, the mass of water produced from 445 g of C_57 H_110 O_6 is: 2 C_57 H_110 O_6( s )+163 O_2( g ) → 114 CO_2( g )+ 110 H_2 O…
For the following reaction, the mass of water produced from $\displaystyle 445$ g of $\displaystyle \mathrm{C}_{57} \mathrm{H}_{110} \mathrm{O}_6$ is :
$$\begin{aligned}
2 \mathrm{C}_{57} \mathrm{H}_{110} \mathrm{O}_6(\mathrm{~s})+163 \mathrm{O}_2(\mathrm{~g}) \rightarrow & 114 \mathrm{CO}_2(\mathrm{~g})+ \\
& 110 \mathrm{H}_2 \mathrm{O}(\mathrm{l})
\end{aligned}
$$
Official answer
(2)
$\displaystyle 495 \mathrm{~g}$
