### A gas occupies 2.2L at 425 kPa. Determine its volume at standard pressure. The temperature does not change.

At room temperature (21°C), the pressure of carbon dioxide in an unopened soda can is 207kPa. Find the pressure of the carbon dioxide in the soda can if left in the trunk of a car on a hot summer day (72°).
