Representation of 1 mole of nitrogen gas
- 1 mole of any substance is defined as the amount of the substance that contains Avogadro's number of particles, which is approximately 6.023 x 10^23.
- Nitrogen gas, represented by the chemical formula N2, is a diatomic molecule made up of two nitrogen atoms.
- Therefore, 1 mole of nitrogen gas contains 6.023 x 10^23 N2 molecules.
Options and their representation
a) 6.023 x 10^23 N2 molecules
- This option is correct as it represents 1 mole of nitrogen gas, which contains Avogadro's number of N2 molecules.
b) 22.4 L of N2 at STP
- This option is also correct as 1 mole of any gas at Standard Temperature and Pressure (STP) occupies 22.4 L of volume.
- Therefore, 1 mole of nitrogen gas at STP occupies 22.4 L of volume.
c) 6.023 x 10^23 nitrogen atoms
- This option is incorrect as 1 mole of nitrogen gas contains 6.023 x 10^23 N2 molecules, which means it contains twice the number of nitrogen atoms.
- Therefore, 1 mole of nitrogen gas contains 2 x 6.023 x 10^23 nitrogen atoms, which is not represented by this option.
d) 28 g of nitrogen
- This option is correct as the molar mass of nitrogen gas (N2) is approximately 28 g/mol.
- Therefore, 1 mole of nitrogen gas weighs 28 g.
- 1 mole of any substance is defined as the amount of the substance that contains Avogadro's number of particles, which is approximately 6.023 x 10^23.
- Nitrogen gas, represented by the chemical formula N2, is a diatomic molecule made up of two nitrogen atoms.
- Therefore, 1 mole of nitrogen gas contains 6.023 x 10^23 N2 molecules.

- This option is also correct as 1 mole of any gas at Standard Temperature and Pressure (STP) occupies 22.4 L of volume.
- Therefore, 1 mole of nitrogen gas at STP occupies 22.4 L of volume.
c) 6.023 x 10^23 nitrogen atoms
- This option is incorrect as 1 mole of nitrogen gas contains 6.023 x 10^23 N2 molecules, which means it contains twice the number of nitrogen atoms.
- Therefore, 1 mole of nitrogen gas contains 2 x 6.023 x 10^23 nitrogen atoms, which is not represented by this option.
d) 28 g of nitrogen
- This option is correct as the molar mass of nitrogen gas (N2) is approximately 28 g/mol.
- Therefore, 1 mole of nitrogen gas weighs 28 g.
