Find the value of in the hydrated salt if the percentage of water of crystallization is . (At. wt. ) — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$\text{Molar mass of } MgSO_4 = 120$. <br>$\frac{18n}{120 + 18n} \times 100 = 51.22$. <br>$1800n = 6146.4 + 921.96n \Rightarrow 878.04n = 6146.4 \Rightarrow n \approx 7$.
