Which has the maximum molecules?

Options

  1. A7 g ~N ₂
  2. B2 H ₂
  3. C16 ~g NO ₂
  4. D16 O ₂

Correct answer

B. 2 H ₂

Step-by-step solution

no. of moles = mass of molecule/ molecular weight. 7 g ~N ₂ 7 28 =0.25 moles 2 ~g H ₂ 2 2 =1 mole 16 ~g NO ₂ 16 46 =0.347 moles 16 ~g O ₂ 16 32 =0.5 moles
