Answer part a and b
![### Understanding Barometric Pressure Measurement
A barometer uses an evacuated, calibrated tube inverted in a pool of mercury. The mercury is open to the atmosphere, and as air pressure increases, the mercury rises in the column. The difference in height between the mercury in the column and the pool equates to atmospheric pressure, measured in linear units like mmHg. This pressure can also be converted into units such as torr, atm, Pa, bar, cm, and inches.
#### Relevant Unit Conversions:
- 1 mmHg = 1 torr
- 1 atm = 760 mmHg
- 1 atm = 1.01325 bar
- 1 Pa = 10⁻⁵ bar
- 1 in = 2.54 cm
- 1 cm = 10 mm
#### Part A
The barometer in **Figure 1** measures atmospheric pressure in millimeters of mercury (mmHg). You need to express the atmospheric pressure \( P \) in inches of mercury (inHg) using five significant figures.
#### Task:
Enter your answer for \( P \) in inches of mercury:
\[ P = \_\_\_\_\_\_ \text{ inHg} \]
#### Part B
Calculate the height of mercury in the column for a pressure of 909 mbar.
#### Task:
Enter the height in millimeters of mercury:
\[ \text{height} = \_\_\_\_\_\_ \text{ mmHg} \]
### Figure Description
- **Figure 1**: Depicts a barometer with a mercury column, showing a range between 753 mmHg and 754 mmHg to measure atmospheric pressure.
Use the given data and conversions to solve the tasks above, ensuring accurate unit handling and proper significant figure usage.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4d09ffa2-b6c2-4e97-915d-74d176d987ab%2F68654b21-33af-46a1-977d-1ca772573671%2F34zvrrd_processed.jpeg&w=3840&q=75)
