Final answer:
To calculate how many moles of H₂O are formed from 3.02 × 10²³ molecules of NH₃, we use Avogadro's number as a conversion factor. Assuming a 1:1 ratio from NH₃ to H₂O in the reaction equation, we can directly determine that 0.501 moles of H₂O would be produced.
Step-by-step explanation:
The student is asking how many moles of H₂O can be formed from 3.02 × 10²³ molecules of NH₃ based on the chemical equation NH₃ + O₂ → N₂ + H₂O. To answer this question, we need to know the balanced chemical equation. However, assuming for a moment that the equation provided is already balanced and that 3 molecules of NH₃ yield 6 atoms of H (which could potentially form 3 molecules of H₂O), the question can be approached using Avogadro's number (6.022 × 10²³ molecules per mole) as a conversion factor.
To find the number of moles of H₂O from NH₃, we will use the ratio that 1 molecule of NH₃ has the potential to form 1 molecule of H₂O (this is a simplification for the sake of the calculation).
- First, find the number of moles of NH₃ using Avogadro's number: (3.02 × 10²³ molecules NH₃) / (6.022 × 10²³ molecules/mol) = 0.501 moles NH₃
- Assuming a 1:1 ratio from NH₃ to H₂O in the balanced equation, the number of moles of H₂O formed would also be 0.501 moles.
