💡 Solution & Explanation

$\Delta V = 1.5 V_{CO} + 1.5 V_{H_2}$? No. <br>$CO + 0.5 O_2 \rightarrow CO_2$ ($\Delta V = 0.5$). <br>$H_2 + 0.5 O_2 \rightarrow H_2O(l)$ ($\Delta V = 1.5$). <br>$0.5x + 1.5y = 21$; $x+y = 20$. <br>$0.5x + 1.5(20-x) = 21 \Rightarrow 0.5x + 30 - 1.5x = 21 \Rightarrow x = 9, y = 11$. Ratio $\approx 2:3$.
