B. 34 grams
Explanation
To solve this problem, we will follow these steps:1. Write down the balanced chemical equation:
2. Calculate the molar mass of nitrogen gas (N2) and ammonia (NH3). The molar mass of nitrogen (N) is approximately 14 g/mol, so for N2, it would be:
The molar mass of ammonia (NH3) is calculated as follows:
3. Determine the number of moles of nitrogen gas used:
4. Use the stoichiometry of the balanced equation to find the moles of ammonia produced. According to the equation, 1 mole of N2 produces 2 moles of NH3.5. Calculate the mass of ammonia produced:
