To determine the number of atoms in the compound $3Na(H_{2}O)_{2}$, we need to break down the compound into its individual atoms.<br /><br />The compound $3Na(H_{2}O)_{2}$ consists of:<br />- 3 sodium atoms (Na)<br />- 2 water molecules (H_{2}O) for each sodium atom<br />- Each water molecule (H_{2}O) consists of 2 hydrogen atoms (H) and 1 oxygen atom (O)<br /><br />So, for each sodium atom, there are 2 water molecules, each containing 2 hydrogen atoms and 1 oxygen atom.<br /><br />Therefore, the total number of atoms in $3Na(H_{2}O)_{2}$ is:<br />3 sodium atoms + (2 water molecules x 3 sodium atoms) x (2 hydrogen atoms + 1 oxygen atom)<br />= 3 sodium atoms + 6 water molecules x (2 hydrogen atoms + 1 oxygen atom)<br />= 3 sodium atoms + 6 hydrogen atoms + 3 oxygen atoms<br />= 12 atoms<br /><br />So, the correct answer is 12.
