One mole of nitrogen gas contains (2)× (6.022 × 10²³)nitrogen atoms.

Question

Quizplus · Accepted Answer

This is the definition of a mole, which is the number of particles (atoms, molecules, etc.) in 12 grams of carbon-12, and is equal to Avogadro's number (6.022 × 10²³) of particles. Therefore, one mole of nitrogen gas contains exactly 6.022 × 10²³ nitrogen atoms. The coefficient 2 in front of the parentheses just indicates that there are two nitrogen atoms in each molecule of nitrogen gas (N₂). So, the total number of nitrogen atoms in one mole of N₂ is 2 × 6.022 × 10²³ = 1.2044 × 10²⁴.
