Work- constant pressure, changing volume

[physics1234]

Find the work done by a gas when it is expanded from a volume of 1.0 L to 3.3 L at a constant pressure of 2.8 atm.

I converted the atm to Pascals by multiplying 2.8 x 101325 to get 283710.

Then I used the formula W=p(deltaV)

so 283710 x (3.3-1.0) = 652533

I don't understand why this is the wrong answer.

Nevermind, I got it :-)

Thanks anyway!

hi brother
so as to your answer be at joule
you must convert the volume to cubic meter m3 , and to convert the pressure to kpa not pascal , by multiplying by 101.3 , try the new answer...

sorry my english is not so good
