Commercial LPG is a mixture of n-butane and iso-butane. Assuming it to be butane (), what is the app — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

Reaction: $C_4H_{10} + 6.5O_2 \to 4CO_2 + 5H_2O$. Moles of butane = $1000\text{g} / 58\text{g/mol} = 17.24\text{ mol}$. Moles of $O_2$ needed = $17.24 \times 6.5 = 112.07\text{ mol}$. Volume at NTP = $112.07 \times 22.4\text{ L} \approx 2510\text{ L}$.
