P compress \( 16 \mathrm{~g} \) of oxygen isothermally at \( 300 \mathrm{~K} \)

W from a pressure of \( 1.01325 \times 10^{3} \mathrm{~N} / \mathrm{m}^{2} \) to \( 1.01325 \times 10^{5} \mathrm{~N} / \mathrm{m}^{2} \) is \( (\ln 100=4.6, \mathrm{R}=8.3 \mathrm{~J} / \mathrm{K}-\mathrm{mol}) \)
(1) \( 5727 \mathrm{~J} \)
(2) \( 11.454 \mathrm{~kJ} \)
(3) \( 123.255 \mathrm{~kJ} \)
(4) \( 1232.55 \mathrm{~kJ} \)
