### Chemistry Problem: Gas Laws

**Question:**

A sample of chlorine gas is confined in a 7.80-L container at 691 torr and 73.0°C.

**Task:**

Calculate the number of moles of gas in the sample.

**Inputs:**

- Volume of the container: 7.80 L
- Pressure: 691 torr
- Temperature: 73.0°C

**Equation:**

Use the Ideal Gas Law: 
\[ PV = nRT \]

- \( P \) = Pressure in atm
- \( V \) = Volume in liters
- \( n \) = Number of moles
- \( R \) = Ideal Gas Constant (\(0.0821 \, \text{L} \cdot \text{atm}/(\text{mol} \cdot \text{K})\))
- \( T \) = Temperature in Kelvin

**Conversion:**

- Convert temperature from Celsius to Kelvin: 
  \[ T(K) = 73.0 + 273.15 = 346.15 \, K \]

- Convert pressure from torr to atm:
  \[ P(\text{atm}) = \frac{691}{760} \approx 0.909 \, \text{atm} \]

**Answer Box:**

\[ \boxed{ \text{mol Cl}_2 } \]

### Note:

Ensure to perform all calculations and solve for the number of moles, \( n \), using the Ideal Gas Law equation.
