Answer: The work done for the given process is -2188.7 J

Explanation:

To calculate the amount of work done for an isothermal process is given by the equation:

$W=-P\Delta V=-P(V_2-V_1)$

W = amount of work done = ?

P = pressure = 50.0 atm

$V_1$ = initial volume = 542 L

$V_2$ = final volume = 974 L

Putting values in above equation, we get:

$W=-50.0atm\times (974-542)L=-21600L.atm$

To convert this into joules, we use the conversion factor:

$1L.atm=101.33J$

So, $-21600L.atm=-21600\times 101.33=-2188728J=-2188.7kJ$

The negative sign indicates the system is doing work.

Hence, the work done for the given process is -2188.7 J
