Mass of Nitrogen and Hydrogen Mixture:
Given that the mass of the nitrogen and hydrogen mixture is 340g.
Yield of Ammonia:
The yield of ammonia is 20%, which means that only 20% of the reactants actually convert into ammonia.
Determining the Mass of Ammonia Produced:
To determine the mass of ammonia produced, we need to consider the balanced chemical equation for the reaction between nitrogen and hydrogen to form ammonia:
N₂ + 3H₂ → 2NH₃
From the balanced equation, we can see that for every 1 mole of nitrogen (N₂) and 3 moles of hydrogen (H₂), we obtain 2 moles of ammonia (NH₃). To calculate the mass of ammonia produced, we need to know the molar masses of nitrogen, hydrogen, and ammonia.
The molar mass of nitrogen (N₂) is approximately 28 g/mol, while the molar mass of hydrogen (H₂) is approximately 2 g/mol. The molar mass of ammonia (NH₃) is approximately 17 g/mol.
Calculating the Moles of Nitrogen and Hydrogen:
To determine the moles of nitrogen and hydrogen in the given mixture, we need to divide their masses by their respective molar masses.
Moles of nitrogen = mass of nitrogen / molar mass of nitrogen
Moles of hydrogen = mass of hydrogen / molar mass of hydrogen
Calculating the Moles of Ammonia Produced:
From the balanced equation, we know that 1 mole of nitrogen reacts to form 2 moles of ammonia. Therefore, the moles of ammonia produced can be calculated as follows:
Moles of ammonia = moles of nitrogen × (2 moles of ammonia / 1 mole of nitrogen)
Calculating the Mass of Ammonia Produced:
To find the mass of ammonia produced, we multiply the moles of ammonia by the molar mass of ammonia:
Mass of ammonia = moles of ammonia × molar mass of ammonia
Since we know that the yield of ammonia is 20%, we can calculate the actual mass of ammonia produced by multiplying the calculated mass by the yield percentage:
Actual mass of ammonia produced = mass of ammonia × (yield percentage / 100)
Conclusion:
By following the steps outlined above, we can determine the mass of ammonia produced from a given mass of nitrogen and hydrogen mixture.
