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 from atmospheres (atm) to kilopascals (kPa), we use the conversion factor:

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

Given that the pressure is [tex]$2.42\text{ atm}$[/tex], we multiply by the conversion factor:

[tex]$$
P_{\text{kPa}} = 2.42\text{ atm} \times 101.325\text{ kPa/atm}
$$[/tex]

Carrying out the multiplication:

[tex]$$
P_{\text{kPa}} \approx 245.2065\text{ kPa}
$$[/tex]

Rounding to the nearest whole number, the pressure is approximately:

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

Thus, the pressure in kilopascals is [tex]$\boxed{245\text{ kPa}}$[/tex].
