Consider the following reaction: 3Fe(s) + 4H₂O(g) ➞ Fe₃O₄(s) + 4H₂(g). To answer the following question: "How many moles of hot
Elodia [21]

Answer: 2

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}

\text{Moles of} Fe_3O_4=\frac{275g}{233.5g/mol}=1.18moles

3Fe(s)+4H_2O(g)\rightarrow Fe_3O_4(s)+4H_2(g)  

According to stoichiometry :

1 mole of Fe_3O_4 are produced by = 4 moles of H_2O

Thus 1.18 moles of Fe_3O_4 will be produced by=\frac{4}{1}\times 1.18=4.72moles  of H_2O

Mass of H_2O=moles\times {\text {Molar mass}}=4.72moles\times 18g/mol=85.0g

Thus 85.0  g of H_2O will be required and 2 steps are required to get the answer.
