Ответ:
The final volume of the gas is 1250 mL
Explanation:
To calculate the amount of work done for an isothermal process is given by the equation:
W = amount of work done for expansion process = -123.3 J = -1.217 L.atm (Conversion factor: 1 L.atm = 101.33 J)
Work done for expansion process is taken as negative
P = pressure = 783 torr = 1.03 atm (Conversion factor: 1 atm = 760 torr)
Putting values in above equation, we get:
Hence, the final volume of the gas is 1250 mL
