How many moles of hot gases are released by the explosion of 0.04 mole of nitroglycerine? — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

For 1 mole, $n_{gas} = PV/RT = (410.5 \times 2.9) / (0.0821 \times 2000) = 1190.45 / 164.2 = 7.25 \text{ mol}$. For 0.04 moles of nitroglycerine, $n = 7.25 \times 0.04 = 0.29 \text{ mol}$. Therefore, correct answer is B.
