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. 1,840 kPa

Answer :

To convert the pressure of a gas from atmospheres (atm) to kilopascals (kPa), we need to use the conversion factor between these two units.

1. Know the Conversion Factor:
- 1 atmosphere (atm) is equivalent to 101.325 kilopascals (kPa).

2. Set Up the Conversion:
- We have a pressure of 2.42 atm that we need to convert to kPa.

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

4. Calculate the Result:
- [tex]\[
\text{Pressure in kPa} = 245.2065
\][/tex]

5. Choose the Closest Answer:
- From the given options, the closest and correct value is 245 kPa.

Thus, the pressure of the gas is 245 kPa.
