Question

The reaction :

$2C+O_2\to 2CO$

is carried out by taking $24$g of carbon and $96$g of $O_2$. The number of moles of $CO$ formed is:

Answer 1

The balanced reaction is given below:
$2C+O_2\to 2CO$
Moles before reaction $\frac{24}{12};\frac{96}{32}$
$=2;=3;=0$
Moles after reaction $0;2;2$
[$\because moleratioofreactionisC:O_2:CO::2:1:2$]
Therefore, $CO$ formed $=$ $2$ mol $=$ $56$ g.
