Heat And Thermodynamics

When 2 moles of a monoatomic gas expands adiabatically from a temperature of $80^{\circ} \mathrm{C}$ to $50^{\circ} \mathrm{C}$, the work done is $W$. The work done when 3 moles of a diatomic gas expands adiabatically from $50^{\circ} \mathrm{C}$ to $20^{\circ} \mathrm{C}$, is
