The percent yield shows the extent to which reactants are converted to products. The percent yield of ammonia is 24.7%
<h3>Percent yield</h3>
The percent yield is obtained from the theoretical yield and the actual yield. The reaction between hydrogen and Nitrogen is;
3H2 + N2 ---->2NH3
If 1 mole of H2 occupies 22.4 dm^3
x moles occupies 12dm^3
x = 0.54 moles
If 1 mole of NH3 occupies 22.4 dm^3
x moles of ammonia occupies 2 dm^3
x = 0.089 moles
Now;
From the reaction equation;
3 moles of hydrogen yields 2 moles of NH3
0.54 moles of hydrogen will yiled 0.54 moles * 2 moles/3 moles
= 0.36 moles of ammonia
Percent yield = 0.089 moles/0.36 moles * 100 = 24.7%
The percent yield of ammonia is 24.7%

The answer to your question is below:
Explanation:
Density: is the ratio between the mass of an object and its volume.
density = mass/ volume. Its units are g/ml, g/cm³ or kg/m³.
What does it tell you about the substance?
Density tells the degree of compactness of a substance. It could tell if the substance is solid or it is porous.
Solar energy or energy from the sun is contained in fossil fuels. Hope you found this helpful! Good luck!
Answer:
76.86g
Explanation:
the molar mass of sulfur trioxide is about 80.06, so 80.06 grams per mol, 0.96*80.06=76.86g
Answer:
6.791
Explanation:
For proper significant figures with addition, you would use the significant figures of the number with lowest decimal place. 6.298 goes to the 10⁻³ place. 0.492712 goes to the 10⁻⁶ place. You will go out to the 10⁻³ place.
6.298 + 0.492712 = 6.790712 ≈ 6.791
