Step 1:Let's solve this step by step:
Step 2:: Determine the molar mass of dinitrogen tetroxide (N₂O₄)
= 92.02 \mathrm{g/mol}
- First, find the atomic masses: - Molar mass calculation:
Step 3:: Calculate the number of moles of N₂O₄
n = \frac{110.0 \mathrm{g}}{92.02 \mathrm{g/mol}} = 1.195 \mathrm{mol}
- Use the mass and molar mass:
Step 4:: Calculate the number of nitrogen atoms
= 1.439 \times 10^{24} \mathrm{atoms}
- Each molecule of N₂O₄ contains 2 nitrogen atoms
Final Answer
1.439 \times 10^{24} \mathrm{atoms}
