Question

1 mole of a gaseous compound $C_5{H}_{10}$ is completely burnt in excess of $O_2$. The moles of $C{O}_2$ formed are:

• A. $5\text{mol}$
• B. $7\text{mol}$
• C. $2\text{mol}$
• D. $3\text{mol}$

Answer 1

The correct option is A $5\text{mol}$

Balancing the combustion reaction:
$C_5{H}_{10}+\frac{15}{2}{O}_2\to 5C{O}_2+5H_{2}O$
1 mol of $C_5{H}_{10}$ will produce 5 mol of $C{O}_2$.
