chem- repost

i don't know how to solve this. looked through all my notes but i'm not sure what kind of formula i am to use or if i even need one! please help me to understand the theory behind this:

"calculate the work need to make room for the products in the combustion of S8(s) to SO2(g) at 1 atm and 0 degree C."

thank you for your time!

    work at constant temp and pressure, will be pressure*deltaV

    in this case, you get two volumes of product

    S8(s)+4O2>>8SO2

    work= p*dV on a per S8 mole basis,

    work= 101.3kPa*4*22.4dm^3*1m^3/1000dm^3

    work= above in Joules

    check my thinking

    thank you for responding, where did you get "4 x 22.4dm^3/1000dm^3" from though?
