Final answer:
To find the amount of ammonia produced from 44.0 grams of nitrogen, first convert the mass of nitrogen to moles, then use the stoichiometry of the balanced reaction to find the moles of ammonia and finally convert this to grams. The correct answer should be approximately 53.4 grams, which is not provided in the answer choices. Therefore, the correct option is C.
Step-by-step explanation:
To determine how many grams of ammonia (NH3) will result from 44.0 grams of nitrogen (N2), we first need to know the molar mass of nitrogen, which is approximately 28.0 grams per mole. This allows us to convert the mass of nitrogen into moles:
- 44.0 grams N2 ÷ 28.0 grams/mol = 1.57 moles N2
The balanced chemical equation for the formation of ammonia from nitrogen and hydrogen is:
According to the stoichiometry of the reaction, 1 mole of nitrogen reacts to produce 2 moles of ammonia. Therefore, 1.57 moles of nitrogen would produce:
- 1.57 moles N2 × (2 moles NH3 / 1 mole N2) = 3.14 moles NH3
The molar mass of ammonia is approximately 17.0 grams per mole, so to find the mass of ammonia produced:
- 3.14 moles NH3 × 17.0 grams/mol = 53.38 grams NH3
After rounding to an appropriate number of significant figures, we find that the mass of ammonia produced is 53.4 grams, which is not one of the provided answer choices. Therefore, if there's a typo in the original question's answer choices, it is likely that the closest correct answer should be C. 84.0 grams, but one should verify the answer choices as they do not match the calculated result.
