Question

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

Answer 1

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

Step-by-step 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=
`(3)/(1)* 4.8=14.4moles` of
`CO_2`

Mass of
`CO_2=moles* {\text {Molar mass}}=14.4moles* 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`
