The weight of one molecule of a compound C ₆₀ H ₁₂₂ is

Options

  1. A1.2 10⁻²⁰ ~g
  2. B5.025 10²³ ~g
  3. C1.4 10⁻²¹ ~g
  4. D6.023 10²³ ~g .

Correct answer

C. 1.4 10⁻²¹ ~g

Step-by-step solution

aligned & Molecular weight of C ₆₀ H ₁₂₂=60 12+1 122 & =842 ~g ~mol ⁻¹ & Weight of 1 mole of C ₆₀ H ₁₂₂ molecules =842 ~g & Weight of 6.023 10²³ molecules =842 ~g & Weight of 1 molecule = 842 6.023 10²³ & =1.4 10⁻²¹ ~g & aligned
