Which of the following solutions have the same molarity? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

A) $n = 4/40 = 0.1 \Rightarrow M = 0.1/0.1 = 1$. <br>B) $n = 5.6/56 = 0.1 \Rightarrow M = 1$. <br>C) $n = 4.9/98 = 0.05 \Rightarrow M = 0.5$. <br>D) $n = 3.65/36.5 = 0.1 \Rightarrow M = 1$.
