If the pressure of a gas is 2.42 atm, what is its pressure in kPa?

A. 0.00318 kPa
B. 0.0239 kPa
C. 245 kPa
D. [tex]$1,840 kPa$[/tex]

Answer :

To convert the pressure from atmospheres (atm) to kilopascals (kPa), we use a standard conversion factor.

1. Understand the Conversion Factor:
- 1 atm is equivalent to approximately 101.325 kPa.

2. Set Up the Conversion:
- Given pressure: 2.42 atm
- Conversion factor: 101.325 kPa per atm

3. Calculate the Pressure in kPa:
- Multiply the given pressure in atm by the conversion factor:
[tex]\[
\text{Pressure in kPa} = 2.42 \, \text{atm} \times 101.325 \, \text{kPa/atm}
\][/tex]

4. Perform the Calculation:
- [tex]\[
\text{Pressure in kPa} = 245.2065 \, \text{kPa}
\][/tex]

5. Choose the Closest Answer:
- From the given choices, 245 kPa is the closest to our calculated value of 245.2065 kPa.

So, the pressure in kPa is approximately 245 kPa.
