Question

the typical pressure of carbon dioxide in an unopened soda can is \\(3.45\text{ atm}\\). calculate the typical pressure in \\(\text{kpa}\\). be sure your answer has the right number of significant digits.

Explanation:

⚡ Using what you learned: Unit Conversions

Step 1: Identify the conversion factor

$$ 1\text{ atm} = 101.325\text{ kPa} $$

Step 2: Set up the conversion

$$ 3.45\text{ atm} \times \frac{101.325\text{ kPa}}{1\text{ atm}} = 349.57125\text{ kPa} $$

Step 3: Round to the correct number of significant digits

The given value \(3.45\text{ atm}\) has 3 significant digits.

$$ 349.57125\text{ kPa} \approx 350.\text{ kPa} \text{ or } 3.50 \times 10^2\text{ kPa} $$

Answer:

350.
