Question

${}^{\prime }{X}^{\prime }$ litres of carbon monoxide is present at $STP$. It is completely oxidized to $C{O}_2$. The volume of $C{O}_2$ formed is $11.207$ litres at $STP$. What is the value of ${}^{\prime }{X}^{\prime }$ in litres?

• A. $22.414$
• B. $11.207$
• C. $5.6035$
• D. $44.828$

Answer 1

The correct option is B $11.207$

$CO+\frac{1}{2}{O}_2\to C{O}_2$
The complete oxidation of $1$ mol ($22.4$ L) of $CO$ gives $1$ mol ($22.4$ L) of $C{O}_2$.
Thus, $11.207$ L of $C{O}_2$ will be produced by complete combustion of $11.207\times \frac{22.4}{22.4}=11.207L$ of $CO$.
