Explanation:
<em>Given:</em>
Mass of ferous (Fe) produced = 750 gram.
<em>To find:</em>
Mass of water produced= ?
<em>Solution:</em>
<em>Molar mass of Fe is 55.84 gram/</em><em>mol</em>
Let's find out the number of moles of ferous produced.
Substituting the given data in above formula.
Now the given reaction is,
- For every 3 mole of production of Fe, 4 mole of waters are produced.
- let for 13.43 moles of Fe x moles of H2O will be produced.
now calculate the number of moles of H2O
mass of one mole of H2O is 18 gram, so we can calculate mass of 17.90 moles.
