Solution Steps

Step 1: Understanding the Relationship Between Moles and Number of Atoms

The relationship between moles and the number of atoms is given by Avogadro's number, which is \(6.022 \times 10^{23}\) atoms/mole. This means that one mole of any element contains \(6.022 \times 10^{23}\) atoms.

Step 2: Calculating the Number of Atoms for Ne

For Neon (Ne), we are given the moles and need to find the number of atoms. Using the formula: \[ \text{Number of atoms} = \text{moles} \times 6.022 \times 10^{23} \] Substituting the given value: \[ \text{Number of atoms for Ne} = 0.468 \times 6.022 \times 10^{23} = 2.818 \times 10^{23} \]

Step 3: Calculating the Moles for Ar

For Argon (Ar), we are given the number of atoms and need to find the moles. Using the formula: \[ \text{Moles} = \frac{\text{Number of atoms}}{6.022 \times 10^{23}} \] Substituting the given value: \[ \text{Moles for Ar} = \frac{3.76 \times 10^{24}}{6.022 \times 10^{23}} = 6.243 \]

Step 4: Calculating the Number of Atoms for Xe

For Xenon (Xe), we are given the moles and need to find the number of atoms. Using the formula: \[ \text{Number of atoms} = \text{moles} \times 6.022 \times 10^{23} \] Substituting the given value: \[ \text{Number of atoms for Xe} = 1.60 \times 6.022 \times 10^{23} = 9.635 \times 10^{23} \]

Final Answer

\[ \begin{array}{|c|c|c|} \hline \text{Element} & \text{Moles} & \text{Number of Atoms} \\ \hline \text{Ne} & 0.468 & \boxed{2.818 \times 10^{23}} \\ \hline \text{Ar} & \boxed{6.243} & 3.76 \times 10^{24} \\ \hline \text{Xe} & 1.60 & \boxed{9.635 \times 10^{23}} \\ \hline \text{He} & - & 1.16 \times 10^{20} \\ \hline \end{array} \]

Question 13 What is the necessary condition for an accused person to be found guilty by a jury? More than 50 percent of the jurors have to find the defendant guilty of the crime. All the jurors have to unanimously agree that the defendant is guilty of the crime. At least half the jurors have to find the defendant guilty of the crime. The jury's verdict has to be approved by the presiding judge.
