In the reaction , how many grams of (at. wt. 27) are required to produce of at STP? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$\text{moles } H_2 = 33.6 / 22.4 = 1.5\text{ mol}$. <br>Ratio $Al : H_2 = 2:3$. <br>$\text{moles } Al = (2/3) \times 1.5 = 1.0\text{ mol}$. <br>$\text{Mass } Al = 1.0 \times 27 = 27\text{ g}$.
