The equivalent weight of a metal is 9. Its chloride has a vapor density of 66.75. What is the valenc — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$MW = 2 \times 66.75 = 133.5$. <br>Formula $MCl_x \Rightarrow MW = At. wt + 35.5x = (E \times x) + 35.5x$. <br>$133.5 = 9x + 35.5x = 44.5x$. <br>$x = 133.5 / 44.5 = 3$.
