Which of the following is the correct value for converting 1.30 atm to pascals (Pa)?

• A. 1.30 atm = 98,000 Pa
• B. 1.30 atm = 101,325 Pa
• C. 1.30 atm = 131,800 Pa
• D. 1.30 atm = 131,900 Pa

Answer: (C)

Verified step by step guidance

1. Recall the conversion factor between atmospheres (atm) and pascals (Pa). The standard conversion is: 1 atm = 101,325 Pa.
2. To convert 1.30 atm to pascals, multiply the given pressure in atm by the conversion factor: \$1.30 \, \text{atm} \times 101,325 \frac{\text{Pa}}{\text{atm}}$.
3. Set up the multiplication carefully, ensuring units cancel properly, leaving the result in pascals (Pa).
4. Perform the multiplication to find the numerical value in pascals (do not round prematurely).
5. Compare your calculated value with the given options to determine which one matches the correct conversion.
