Question

How many grams of H20 will be produced if 120 grams of Iron are produced ? Use the following equation: Fe304 O4+H2 Fe+ * H20 *

Answer 1

Ans:-

Reaction is

$Fe_3O_4+4H_2\rightarrow3Fe+4H_2O$

So according to the question 120g Iron are produced. Firstly we found mole of iron.

Mole of Iron $=\dfrac{120}{55.845}=2.148 mole$

So $2.148$ moles of Iron are produced and we have seen that from the reaction that according to stoichiometry that $3mole$ of Iron produced with respect $4$ moles of $H_2O$ then

$\Rightarrow$ moles of $H_2O$ produced $=$ $\dfrac{4}{3}\times2.148=2.86$ moles

$\Rightarrow$ Gram of $H_2O$ produced $= 2.86\times18=51.48$ gm
