Answer part A, B, and C
**Post Lecture Homework Chapter 06 Gases - Attempt 2**

**Gas Pressure**

### Learning Goal:
To understand several methods of measuring gas pressure.

Gases exert a measurable pressure (\( P \)) on the walls of their container. The SI unit for pressure is the pascal (\( \text{Pa} \)). Other pressure units frequently used in chemistry are millimeters of mercury (\( \text{mmHg} \)) and atmospheres (\( \text{atm} \)). You can convert between units of pressure using conversion factors such as those indicated below.

1 atm = 760 mmHg = 101,325 Pa

**Figure 1: Diagram Explanation**

- The diagram shows an open-end mercury-filled manometer.
- On the left, there is a green bulb labeled "Gas," which is connected to one side of the manometer.
- The manometer is U-shaped with one side open to the atmosphere.
- There is a difference in the mercury levels between the sides, with the side connected to the gas being higher.
- The height difference between the levels of mercury is marked as 18 cm.
