#### Problem 1: Combined Gas Law Calculation
**Question:**
Calculate the pressure of 3.50 Liters of a gas at 25.0°C if it has a volume of 4.50 Liters at STP. Hint: the temperature and pressure of STP is in your notes. (Combined)
**Details:**
To solve this problem, you will use the Combined Gas Law:
\[ \frac{P_1 \cdot V_1}{T_1} = \frac{P_2 \cdot V_2}{T_2} \]
Where:
- \(P_1\) and \(P_2\) are the initial and final pressures,
- \(V_1\) and \(V_2\) are the initial and final volumes,
- \(T_1\) and \(T_2\) are the initial and final temperatures (in Kelvin).
Convert temperatures to Kelvin (K = °C + 273).
#### Problem 2: Charles' Law Calculation
**Question:**
A gas occupies 35.1 Liters at a temperature of 105.0°C. What will its volume be if it is cooled to 25.0°C? (Charles Law)
**Details:**
To solve this problem, you will use Charles' Law:
\[ \frac{V_1}{T_1} = \frac{V_2}{T_2} \]
Where:
- \(V_1\) and \(V_2\) are the initial and final volumes,
- \(T_1\) and \(T_2\) are the initial and final temperatures (in Kelvin).
Convert temperatures to Kelvin (K = °C + 273).
For both problems, ensure to solve for the unknown variable by appropriately rearranging the given equation. Additionally, make sure to maintain consistent units throughout the calculation.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F60897a88-2068-4dd8-9c40-1650c1de52f4%2F3f99f76d-3f93-4494-9e84-9b3120662307%2F623z0do_processed.jpeg&w=3840&q=75)
