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

First, find the moles of gas released per mole of nitroglycerine. For 1 mole, the products have P = 410.5 atm, V = 2.9 L, T = 1727 + 273 = 2000 K. n_products = PV / RT = 410.5 × 2.9 / (0.0821 × 2000) = 1190.45 / 164.2 = 7.25 mol of gas. For 0.04 mole of nitroglycerine, the moles of hot gases released is 0.04 × 7.25 = 0.29 mol.
