# How many moles of Al are needed to react completely with 1.2 mol FeO in the reaction 2Al + 3FeO -> 3Fe + Al_2O_3?

0.8 moles

#### Explanation:

from the equation we can see,
$2$ mole $A l$ is needed to react completely with $3$ mole $F e O$

so,
$3$ moles of $F e O$ needs $2$ moles $A l$
so, $1$ mole $F e O$ needs $\frac{2}{3}$ moles $A l$

so, $1.2$mol $F e O$ needs $\frac{2 \times 1.2}{3}$moles $A l$

$= 0.8$moles $A l$
