Answer:
1.89mol
Explanation:
The entropy change during free expansion is express as
Where S is the entropy of the system,
n is the amount of mole
R is the gas constant = 8.314 and
V is the volume occupied at the initial and final stage
since the process is n adiabatic free expansion, the entropy of the system is constant. Hence we can re-write the equation as
where the and
and
Now if we substitute in values we arrive at
