Find the value of in the formula if of the salt yields of anhydrous salt on heating. — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$\text{Mass } H_2O = 2.48 - 1.58 = 0.90\text{ g}$. <br>$\text{moles } H_2O = 0.90 / 18 = 0.05\text{ mol}$. <br>$\text{moles anhydrous } Na_2S_2O_3 = 1.58 / 158 = 0.01\text{ mol}$. <br>$n = 0.05 / 0.01 = 5$.
