What is the number of CO ₂ molecules in 45.42 litre at STP? (Consider molar volume of gas at STP =22.71 ~L ~mol ⁻¹ )

Options

  1. A0.913 10²⁴
  2. B1.806 10²⁴
  3. C1.501 10²⁴
  4. D1.204 10²⁴

Correct answer

D. 1.204 10²⁴

Step-by-step solution

Number of moles = 45.42 22.71 =2 or 2 6.02 10²³=1.204 10²⁴ molecules
