Answer:

D) 373 mm Hg.

Explanation:

We can solve this problem by keeping in mind<em> Dalton's law of partial pressures</em>, which states that the total pressure of a mixture of gases is equal to the sum of each gas' partial pressures. In other words, for this case:

  • Total Pressure = Ne Pressure + CO₂ Pressure + O₂ Pressure + H₂ Pressure
  • 1245 mm Hg = Ne Pressure + 145 mm Hg + 228 mm Hg + 499 mm Hg
  • Ne Pressure = 373 mm Hg

The answer is option D) 373 mm Hg.
