Question

1 mole of Argon gas contains ______number of fundamental particles.

Answer 1

• 1 mole of Argon gas contains 58 of fundamental particles.
• Fundamental particles are Proton, Neutron, and Electron.
• Atomic number of Argon =18.
• The atomic mass of Argon =40.
• Number of Proton= number of electron= Atomic number=18.
• Number of Neutrons =Atomic mass - Atomic Number = 40-18=22.
• So 1 mole of Argon contains 18 +18 + 22 = 58.

Hence, 1 mole of Argon gas contains 58 number of fundamental particles.
