What mass of CO2 can be produced from the decomposition of 4.8 moles of Fe2(CO3)3?
gavmur [86]

Answer: 633.6 g of CO_2 can be produced from the decomposition of 4.8 moles of Fe_2(CO_3)_3

Explanation:

The balanced chemical equation for decomposition of Fe_2(CO_3)_2 is :

Fe_2(CO_3)_2\rightarrow Fe_2O_3+3CO_2

According to stoichiometry :

1 mole of Fe_2(CO_3)_2 produce = 3 moles of CO_2

Thus 4.8 moles of Fe_2(CO_3)_2 will rproduce=\frac{3}{1}\times 4.8=14.4moles  of CO_2

Mass of CO_2=moles\times {\text {Molar mass}}=14.4moles\times 44g/mol=633.6g

Thus 633.6 g of CO_2 can be produced from the decomposition of 4.8 moles of Fe_2(CO_3)_3
