Solution

$$ \begin{aligned} & \mathrm{C}_6 \mathrm{H}_{12} \mathrm{O}_{6(\mathrm{~s})}+6 \mathrm{O}_{2(\mathrm{~g})} \rightarrow 6 \mathrm{CO}_{2(\mathrm{~g})}+6 \mathrm{H}_2 \mathrm{O}_{(\ell)} \frac{900}{180} \\ & =5 \mathrm{~mol} \quad 30 \mathrm{~mol} \end{aligned} $$ Mass of $\mathrm{O}_2$ required $=30 \times 32=960 \mathrm{gm}$
