Final answer:
The work required to expand the volume of a pump from 0.0 L to 2.2 L against an external pressure of 1.0 atm is 222.904 J.
Step-by-step explanation:
The amount of work required to expand the volume of a pump from 0.0 L to 2.2 L against an external pressure of 1.0 atm can be found using the formula work = pressure × change in volume. We need to convert the pressure to pascals and the volume to cubic meters to use SI units. Using the conversion factor 1 L'atm = 101.32 J, we have:
- Change in volume = 2.2 L - 0.0 L = 2.2 L
- Work = 1.0 atm × 2.2 L = 2.2 L'atm
- Work in joules = 2.2 L'atm × 101.32 J/L'atm = 222.904 J
Hence, the work required is 222.904 J (joules).
