Find the mass of oxygen in grams produced by the decomposition of 100.0 g of CO2

SSSSS [86.1K]

The balanced chemical equation is :

$2CO_2->2CO+O_2\\\\$

Moles of $CO_2$ ,

$n = \dfrac{100\ g}{44.01\ g/mol}\\\\n=2.27\ mol$

Now, by given chemical equation , we can see 2 mole of $CO_2$ react with 1 mole of $O_2$ .

So , 2.27 mole react with :

$N=\dfrac{2.27}{2}\ mol\\\\N=1.135\ mol$

Mass of oxygen is :

$M = N \times 16\\\\M=1.135\times 16\ g\\\\M =18.16\ g$

Therefore, mass of oxygen in grams produced is 18.16 g.

Hence, this is the required solution.
