Question 1 As shown in figure below, seawater (3.5 wt%, density 1.02 g/cm³) at 100 kg/s and river water (density 1.00 g/cm³) at 200 kg/s converge continuously. Calculate the molar concentration (mol/m³) of sodium chloride (NaCl) and water in seawater, the mole fraction of NaCl (ratio of the amount of NaCl to the total amount of seawater), and the flow rate of water and NaCl in the mixed water (kg/m³). Note that the molecular weights of water and NaCl are 18.0 (g/mol) and 58.4 (g/mol), respectively. Sea water 100 kg/s H₂O ?? kg/s NaCl ?? kg/s = River water 200 kg/s H₂O 200 kg/s Mixed water 300 kg/s H₂O 200+ ?? kg/s NaCl ?? kg/s NaCl 0 kg/s 2
