To calculate the percentage of nitrogen in the organic compound, we need to determine the amount of nitrogen present in the 0.2 g sample.
First, we need to calculate the number of moles of nitrogen gas evolved during the Dumas method.
1. Calculate the number of moles of nitrogen gas:
- Molar volume of nitrogen gas at STP = 22.4 L
- Volume of nitrogen gas evolved = 22.400 mL = 22.400 * 10^(-3) L
- Moles of nitrogen gas = (Volume of nitrogen gas evolved)/(Molar volume of nitrogen gas)
= (22.400 * 10^(-3) L) / (22.4 L)
= 1 * 10^(-3) mol
Next, we need to calculate the number of moles of nitrogen in the compound.
2. Calculate the number of moles of nitrogen in the compound:
- Molar mass of nitrogen gas (N2) = 28 g/mol
- Moles of nitrogen in the compound = Moles of nitrogen gas * (Molar mass of nitrogen gas)/(Molar mass of N2)
= (1 * 10^(-3) mol) * (28 g/mol) / (28 g/mol)
= 1 * 10^(-3) mol
Finally, we can calculate the percentage of nitrogen in the compound.
3. Calculate the percentage of nitrogen in the compound:
- Mass of nitrogen in the compound = Moles of nitrogen in the compound * Molar mass of N2
= (1 * 10^(-3) mol) * (28 g/mol)
= 0.028 g
- Percentage of nitrogen in the compound = (Mass of nitrogen in the compound)/(Mass of the sample) * 100
= (0.028 g)/(0.2 g) * 100
= 14%
Therefore, the percentage of nitrogen in the compound is 14%.
First, we need to calculate the number of moles of nitrogen gas evolved during the Dumas method.
1. Calculate the number of moles of nitrogen gas:
- Molar volume of nitrogen gas at STP = 22.4 L
- Volume of nitrogen gas evolved = 22.400 mL = 22.400 * 10^(-3) L
- Moles of nitrogen gas = (Volume of nitrogen gas evolved)/(Molar volume of nitrogen gas)
= (22.400 * 10^(-3) L) / (22.4 L)
= 1 * 10^(-3) mol
Next, we need to calculate the number of moles of nitrogen in the compound.
2. Calculate the number of moles of nitrogen in the compound:
- Molar mass of nitrogen gas (N2) = 28 g/mol
- Moles of nitrogen in the compound = Moles of nitrogen gas * (Molar mass of nitrogen gas)/(Molar mass of N2)
= (1 * 10^(-3) mol) * (28 g/mol) / (28 g/mol)
= 1 * 10^(-3) mol
Finally, we can calculate the percentage of nitrogen in the compound.
3. Calculate the percentage of nitrogen in the compound:
- Mass of nitrogen in the compound = Moles of nitrogen in the compound * Molar mass of N2
= (1 * 10^(-3) mol) * (28 g/mol)
= 0.028 g
- Percentage of nitrogen in the compound = (Mass of nitrogen in the compound)/(Mass of the sample) * 100
= (0.028 g)/(0.2 g) * 100
= 14%
Therefore, the percentage of nitrogen in the compound is 14%.
