Answer: The amount of work done by the ideal gas is 42494.8 J

Explanation:

To calculate the work done for isothermal, reversible compression process, we use the equation:

W=-2.303nRT\log(\frac{V_2}{V_1})

where,

W = work done

n = number of moles = 2 mole

R = Gas constant = 8.314 J/mol.K

T = Temperature of the gas = 300 K

V_1 = initial volume = 5m^3=5000dm^3    (Conversion factor:  1m^3=1000dm^3 )

V_2 = final volume = 1dm^3

Putting values in above equation, we get:

W=-2.303\times 2mol\times 8.314J/mol.K\times 300K\times \log(\frac{1}{5000})\\\\W=42494.8J

Hence, the amount of work done by the ideal gas is 42494.8 J
