Molar Mass and Mole Calculation
- The molar mass of a substance is the mass of one mole of that substance, usually expressed in grams per mole (g/mol).
- The molar mass of nitrogen gas (N2) can be calculated by adding the atomic masses of two nitrogen atoms.
- The molar mass of a single nitrogen atom (N) is approximately 14 g/mol.
EXPLANATION:
- For nitrogen gas (N2):
- The molar mass of N2 = 14 g/mol (for one N atom) × 2 = 28 g/mol
- To find the mass of 0.5 mole of N2 gas, we use the formula:
- Mass = Number of moles × Molar mass
- Mass = 0.5 moles × 28 g/mol
- Mass = 14 grams
Therefore, the mass of 0.5 mole of N2 gas is 14 grams.
