Step 1:Let's solve this step by step:
Step 2:: Determine the molar mass of hydrazine (N₂H₄)
= 32.052 \mathrm{g/mol}
- Atomic mass of hydrogen (H): 1.008 \mathrm{g/mol}
Step 3:: Calculate the number of moles of hydrazine
= 3.431 \mathrm{mol}
- Moles of N₂H₄ = \frac{110.0 \mathrm{g}}{32.052 \mathrm{g/mol}}
Step 4:: Calculate the number of nitrogen atoms
= 4.131 \times 10^{24} \mathrm{atoms}
- Each molecule of N₂H₄ contains 2 nitrogen atoms
Final Answer
4.131 \times 10^{24} \mathrm{atoms}
