How would I calculate the work done by the gas molecules?

Homework Statement

Hello, I just need help figuring out how to calculate the work done by the gas molecules for my physics homework :)
Formula given: W=Px∆V (W=work, P=pressure, and V=volume)
What I know: So my calculated volume is 1.7x10^-22m^3.
Pressure=0.25 A t m (atmospheric pressure)
I just need help figuring out how I would multiply the two together.

Homework Equations

The Attempt at a Solution

Would I change 0.25 A t m to scientific notation? So it would be 2.5x10^-1, then if I multiplied it by 1.7x10^-22m^3 it would be 4.25x10^-23 Joules of work done?

To get the work in joules, it is best to convert the pressure to SI units (pascal).

But I suspect you are wrong about the volume change.

Ok, so 0.25 A t m = 25331.25 Pascal, which is 2.533125x10^4 in scientific notation. Would I then just multiply the two together? And no, I did all my calculations correct, the volume change is 1.7x10^-22m^3, I even had another person on here help me achieve that answer.
