For an ideal gas mixture of and with average molecular weight 3: — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$3 = 2x + 4(1-x) \Rightarrow 3 = 2x + 4 - 4x \Rightarrow 2x = 1 \Rightarrow x = 0.5$. Mole fraction 0.5 means mole, volume, and pressure ratios are all $1:1$. Mass ratio $= (0.5 \times 2) : (0.5 \times 4) = 1:2$.
