Question

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

Explanation:

Step1: Use the conversion factor

We know that \(1\space atm = 101.325\space kPa\).

Step2: Set up the conversion

To convert \(3.45\space atm\) to \(kPa\), we multiply \(3.45\) by \(101.325\). So, \(P = 3.45\times101.325\).

Step3: Perform the calculation

Step4: Consider significant digits

The given value \(3.45\) has three significant digits. So, we round \(349.57125\) to three significant digits. \(349.57125\approx350\) (when rounded to three significant digits, \(349.57125\) is \(3.50\times 10^{2}\) in scientific - notation, but as a whole number with three significant digits, it is \(350\)).

Answer:

\(350\)
