Answer: 6.022 x 1023 particles.
- A 6.022 x 1023 particles
- B 1 particle overall
- C 22.4 particles in most cases
- D 12 particles under typical conditions
Correct answer: A. 6.022 x 1023 particles
Explanation: One mole contains Avogadro's number of particles, which is 6.022 x 1023 particles.
Mass connects to moles via molar mass, and moles connect to particle count via Avogadro's number or to gas volume via the 22.4 L/mol rule at STP.
Concept context
The mole is chemistry's counting unit. Learn to relate mass, volume, and number of particles using Avogadro's number and molar mass, the foundation of all stoichiometry and reaction calculations.
