Given the following equation, what is the correct form of the conversion factor needed to convert the number of moles of O₂ to t

djverab [1.8K]

Answer : The correct option is (c) $\frac{2\text{ mole of }Fe_2O_3}{3\text{ mole of }O_2}$

Explanation :

The given balanced chemical reaction is,

$4Fe(s)+3O_2(g)\rightarrow 2Fe_2O_3(s)$

From the balanced chemical reaction, we conclude that

As, 3 moles of $O_2$ react to give 2 mole of $Fe_2O_3$

So, 1 mole of $O_2$ react to give $\frac{2\text{ mole of }Fe_2O_3}{3\text{ mole of }O_2}$ moles of $Fe_2O_3$

Thus, the conversion factor needed to convert the number of moles of $O_2$ to the number of moles of $Fe_2O_3$ produced is $\frac{2\text{ mole of }Fe_2O_3}{3\text{ mole of }O_2}$

Hence, the correct option is (c) $\frac{2\text{ mole of }Fe_2O_3}{3\text{ mole of }O_2}$
