One mole of an ideal gas is expanded isothermally at \( 300 \mathrm{~K} \) until its volume is tripled. Find the values of \( \Delta \mathrm{S}_{\text {total }} \) under the condition.

Expansion is carried out irreversibly where \( 900 \mathrm{~J} \) of heat is less absorbed than expansion is carried out reversibly. (Approximate integer value, Used e \( \mathrm{e}^{1.09}=3 \& 8.314 \times 1.09=9 \) )
