suppose 355 gallons of a mixture containing 4 wt nacl sodium chloride
Suppose 355 gallons of a mixture containing 4 wt% NaCl (sodium chloride) and 96 wt% water(solution density 1.0253 g/cm) is mixed with an unknown volume of solution that is 26 wt% NaCl and 74 wt% water(solution density 1.1944 g/cm³). Complete the questions to determine the volume of the second feed solution required to produce a mixture containing 19 wt% NaCl. Label the flow chart of the mixing process. Do not leave any spaces empty.
How many unknowns are in the problem statement?
Which independent equations can be written to solve for the volume of the second feed solution? |The sum of the weight fractions of the product solution is equal to 1. volume balance on NaCl The density of the 26 wt% NaCl solution relates the solution mass to volume. volume balance on the total amount of fluid The density of the 4 wt NaCl solution 'relates the solution mass to volume. mass balance on NaCl volume balance on water The sum of the weight fractions of the 4 wt NaCl solution is equal to 1. mass balance on water The sum of the weight fractions of the 26 wt% NaCl solution is equal to 1.
