Final answer:
To find the new volume of carbon dioxide at standard pressure, we use Boyle's law, resulting in a new volume of 7.19 liters when the pressure is decreased from 107 kPa to standard pressure (101.3 kPa).
Step-by-step explanation:
The question involves using the gas laws to determine the new volume of carbon dioxide when the pressure is decreased to standard pressure. By applying Boyle's law, which states that the product of the pressure and volume is constant for a given mass of confined gas as long as the temperature is unchanged (P1V1 = P2V2), we can calculate the new volume at standard pressure. The standard pressure is 101.3 kPa (1 atm), so when the pressure decreases from 107 kPa to 101.3 kPa, the volume will increase accordingly. To find the new volume (V2), we rearrange the formula to V2 = (P1V1) / P2 and plug in the given values. Therefore, V2 = (107 kPa * 6.79 L) / 101.3 kPa = 7.19 L. This means if we decrease the pressure to standard pressure, there would be 7.19 liters of carbon dioxide.
