Which of the following is the correct pressure in atmospheres for a measurement of 1400 mm Hg?

• A. 1.84 atm
• B. 2.13 atm
• C. 1.03 atm
• D. 0.921 atm

Answer: (A)

Verified step by step guidance

1. Identify the conversion factor between mm Hg and atmospheres. The standard conversion is \$1\ \text{atm} = 760\ \text{mm Hg}$.
2. Set up the conversion equation to convert 1400 mm Hg to atmospheres using the conversion factor: \(\text{Pressure in atm} = \frac{1400\ \text{mm Hg}}{760\ \text{mm Hg/atm}}\).
3. Perform the division to find the pressure in atmospheres. This step involves dividing 1400 by 760.
4. Compare the calculated value to the given answer choices to determine which one matches the converted pressure.
5. Select the answer choice closest to the calculated pressure in atmospheres as the correct pressure.
