# A particulate representation of a \(10.0\text{ mL}\) sample of \(0.10\text{ M }\text{NaCl(aq)}\) is shown below (water molecules are omitted for clarity).

Which of the following particulate diagrams best represents a \(10.0\text{ mL}\) sample of \(0.10\text{ M }\text{MgCl}_2\text{(aq)}\) drawn to the same scale?

A particulate representation of a \(10.0\text{ mL}\) sample of \(0.10\text{ M }\text{NaCl(aq)}\) is shown below (water molecules are omitted for clarity).

Which of the following particulate diagrams best represents a \(10.0\text{ mL}\) sample of \(0.10\text{ M }\text{MgCl}_2\text{(aq)}\) drawn to the same scale?

![A single square diagram represents a microscopic sample of an aqueous solution. To the right of the square, a legend defines two symbols: an open white circle represents \(\text{Na}^+\), and a solid black circle represents \(\text{Cl}^-\). Inside the square boundary, there are exactly 4 open white circles and exactly 4 solid black circles. The 8 total ions are evenly dispersed throughout the interior area with alternating spacing, and no ions contact one another. All circles have the same diameter. Water molecules are omitted for clarity. No other particles, labels, text, or annotations appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1787300219-r3sJqA.jpg)
