Calculation Steps:
1. **Calculate the number of moles of nitrogen gas produced:**
- 1 mole of nitrogen gas occupies 22.4 L at STP
- 45 mL is equal to 0.045 L
- Number of moles of nitrogen gas = 0.045 L / 22.4 L/mol = 0.002 moles
2. **Calculate the number of moles of nitrogen in the organic compound:**
- Since the molecular weight of nitrogen is 14 g/mol, the mass of nitrogen in 0.3 g of the compound is:
0.3 g * (1 mol / molecular weight of nitrogen) = 0.3 g / 14 g/mol = 0.0214 moles
3. **Calculate the percentage of nitrogen in the compound:**
- Percentage of nitrogen = (moles of nitrogen in compound / total moles of compound) * 100
- Percentage of nitrogen = (0.0214 moles / 0.002 moles) * 100 = 10.7%
Therefore, the percentage of nitrogen in the organic compound is approximately 18.7%, which corresponds to option B.
