Answer :
- Convert pressure from atm to kPa using the conversion factor 1 atm = 101.325 kPa.
- Multiply the given pressure in atm by the conversion factor: $2.42 \times 101.325$.
- Calculate the result: $2.42 \times 101.325 = 245.2065$.
- The pressure in kPa is approximately $\boxed{245}$ kPa.
### Explanation
1. Problem Analysis
We are given the pressure of a gas as 2.42 atm and asked to convert it to kPa. We know that 1 atm is equal to 101.325 kPa.
2. Conversion Formula
To convert the pressure from atm to kPa, we multiply the given pressure in atm by the conversion factor: Pressure (kPa) = Pressure (atm) * 101.325 (kPa/atm).
3. Calculation
Pressure (kPa) = 2.42 atm * 101.325 kPa/atm = 245.2065 kPa.
4. Final Answer
Therefore, the pressure of the gas in kPa is approximately 245.2065 kPa. Looking at the options, the closest value is 245 kPa.
### Examples
Understanding pressure conversions is crucial in various fields, such as meteorology, where atmospheric pressure is measured in different units like atm, kPa, or mmHg. For example, if a weather report states the atmospheric pressure is 101.325 kPa, you can convert it to atm to understand it in a different context, especially if you are familiar with atm as a unit. This conversion helps in comparing and interpreting weather data across different regions and sources.
