An aqueous solution of sodium chloride containing 0.2 wt% NaCl and 99.8% water is fed at a rate of 2.0 kg/s into a distillation unit. Pure water vapor exits the top of the unit via stream 2 at a rate of 1.6 kg/s, while the remaining sodium chloride solution (now with a mass fraction x kg NaCl/kg) exits the bottom of the unit via stream 3 at a steady rate of m3 kg/s. What is the mass fraction of NaCl in the stream exiting the bottom of the unit? O 0.001 kg NaCl/kg O 0.010 kg NaCl/kg O 0.004 kg NaCl/kg O 0.400 kg NaCl/kg O None of the above

Question
Help with the following question
Transcribed Image Text:An aqueous solution of sodium chloride containing 0.2 wt% NaCl and 99.8% water is fed at a rate of 2.0 kg/s into a distillation unit.
Pure water vapor exits the top of the unit via stream 2 at a rate of 1.6 kg/s, while the remaining sodium chloride solution (now with a
mass fraction x kg NaCl/kg) exits the bottom of the unit via stream 3 at a steady rate of m3 kg/s. What is the mass fraction of NaCl in
the stream exiting the bottom of the unit?
O 0.001 kg NaCl/kg
O 0.010 kg NaCl/kg
O 0.004 kg NaCl/kg
O 0.400 kg NaCl/kg
O None of the above
