In of solution: — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

$\text{Moles} = 0.5 \times 0.1 = 0.05\text{ mol}$. <br>$K_2SO_4 \rightarrow 2K^+ + SO_4^{2-}$. <br>$\text{Moles } K^+ = 0.1 \Rightarrow [K^+] = 0.1/0.5 = 0.2\text{ M}$. <br>$\text{Moles } SO_4^{2-} = 0.05 \Rightarrow [SO_4^{2-}] = 0.05/0.5 = 0.1\text{ M}$.
