A container contains equal masses of H ₂, He , CO ₂ and Ne at a certain temperature. Which of the following gas exerts maximum partial pressure?

Options

  1. AH ₂
  2. BHe
  3. CCO ₂
  4. DNe

Correct answer

A. H ₂

Step-by-step solution

According to Dalton's law of partial pressures and the ideal gas law PV = nRT , for a gas mixture at constant temperature and volume, partial pressure P_i is proportional to the number of moles n_i : P_i n_i . With equal masses m of each gas, the number of moles for each gas is: n_ H ₂ = m 2 , n_ He = m 4 , n_ CO ₂ = m 44 , n_ Ne = m 20 Comparing the denominators 2 Final answer: A
