$A$ $5 \, L$ cylinder contains $10 \, mol$ of $O_2$ gas at $27 \, ^\circ C$. Due to a leak,the gas escapes into the atmosphere until the pressure inside the cylinder equals the atmospheric pressure $(1.0 \, atm)$. What is the work done by the gas?

  • A
    $-0.5 \times 101.3 \, L \cdot atm$
  • B
    $-1.5 \times 201.3 \, L \cdot atm$
  • C
    $-1 \times 241.3 \, L \cdot atm$
  • D
    $-2 \times 101.3 \, L \cdot atm$
