A gas stream containing acetone in air flows from a solvent recovery unit at a rate of $142\frac{L}{s}$ at $150\mathrm{.}0C$ and $1\mathrm{.}3$atm. The stream flows

Calculate the molar flow rates of air and acetone into and out of the condenser.

into a condenser which condenses most of the acetone, and the liquid and gas outlet streams are in equilibrium at $0\mathrm{.}0C$ and $3\mathrm{.}0$atm.

Shaft work is delivered to the system at a rate of $14\mathrm{.}5kW$ to achieve the compression from $1\mathrm{.}3$atm to $3\mathrm{.}0$atm. To determine the

condenser feed stream composition, a $3\mathrm{.}00-$liter sample of the gas is taken and cooled to a temperature at which essentially all the

acetone in the sample is recovered as a liquid. The liquid is poured into an empty flask with a mass of $4\mathrm{.}017g.$ The flask containing the

liquid acetone is weighed and found to have a mass of $4\mathrm{.}973g.$

Attempts: $3$ of $3$ used

$V_0^{}=142\frac{L}{s},V_s=3\mathrm{.}00L,P_1=3\mathrm{.}0$atm

$T_0=150\mathrm{.}0C,W_s^{}=14\mathrm{.}5kW,T_2=0\mathrm{.}0C$

$P_0=1\mathrm{.}3$atm,$T_1=0\mathrm{.}0C,P_2=3\mathrm{.}0$atm

Perform an energy balance over the condenser to determine $Q^{}(kW).$ Pay careful attention to the sign of $Q^{}.$ Please help me find Q
