How many molecules are present in 2 moles of CO₂?

Correct option is B

The correct answer is (b) 1.2044 × 10²⁴

Explanation:

• The number of molecules in one mole of a substance is given by Avogadro's number, which is approximately 6.022 × 10²³ molecules per mole.
• Therefore, for 2 moles of CO₂, the total number of molecules will be:
  2 moles × 6.022 × 10²³ molecules/mole = 1.2044 × 10²⁴ molecules.
• So, there are 1.2044 × 10²⁴ molecules of CO₂ in 2 moles.

Information Booster:

• Avogadro's number (6.022 × 10²³) is the number of entities (atoms, molecules, ions, etc.) in one mole of any substance.
• The number of molecules is directly proportional to the number of moles. If you have more moles, you have more molecules.

Additional Knowledge:
(a) 6.022 × 10²³: This is the number of molecules in 1 mole, not 2 moles.
(c) 3.011 × 10²³: This would be the number of molecules in 1 mole of CO₂.
(d) 13.044 × 10²³: This is an incorrect option for 2 moles of CO₂.
