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. 1840 kPa

Answer :

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

[tex]\[ 1 \text{ atm} = 101.325 \text{ kPa} \][/tex]

Here's the step-by-step process to find the pressure in kPa:

1. Identify the given pressure in atm:
The pressure is given as 2.42 atm.

2. Use the conversion factor:
To convert this pressure to kPa, multiply the given pressure by the conversion factor (101.325 kPa per atm).

3. Perform the multiplication:
[tex]\[ \text{Pressure in kPa} = 2.42 \text{ atm} \times 101.325 \text{ kPa/atm} \][/tex]

4. Calculate the result:
[tex]\[ \text{Pressure in kPa} = 2.42 \times 101.325 = 245.2065 \text{ kPa} \][/tex]

Therefore, the pressure of 2.42 atm is approximately [tex]\( 245 \text{ kPa} \)[/tex].

So, the correct answer is:

[tex]\[ 245 \text{ kPa} \][/tex]
