A feed of $50$ mole$\%$ acetone $-50$ mole$\%$ water is sent to a flash drum operating at P $=1$ bar and T $=80$C$.$ The schematic of the flash drum is shown in Figure $2.$ The liquid and vapor phases coming out of the flash drum are in equilibrium. It is observed that in the vapor phase, the acetone composition is $68$ mole$\%.$ Using Raoult$$s law, estimate the composition of water in the liquid phase $($in mole$\%).$ The Antoine$$s constants for acetone are: A$=4\mathrm{.}42448$ ; B$=1312\mathrm{.}253$ ; C$=-32\mathrm{.}445.$ log$10($P$^$v$)=$ A $-($ B$/($T$+$C$))$ In the Antoine$$s equation, P$^$v is in bar and T is in KVapor $68$ mole$\%$ acetone Flash drum $50$ mole$\%$ acetone T$=80$C$,$P$=1$ bar $50$ mole$\%$ water
