The final partial pressure of NH₃ gas in the bulb is — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

As calculated in the previous part, the sum of partial pressures of NH₃ and HCl is 680 mm Hg. Since they are produced in equimolar amounts, the partial pressure of NH₃ is $680 / 2 = 340 \text{ mm Hg}$. Therefore, correct answer is D.
