Question: two aqueous hydrogen bromide solutions containing 60 wt hbr sg10402...

Question details

Two aqueous hydrogen bromide solutions containing 6.0 wt% HBr (SG-10402) and 50.0 wt% HBr (SG- 1.5127) are mixed to form 1150 kg/hr of a 2.86 molar HBr solution (SG 1.1557). Below is the proces flow diagram. mn kg/hr solution (unknown) Vi L/hr solution (unknown) X1 = 6.0 wt% HBr X2 wt% water (unknown) m3 1150 kg/hr solution V3 L/hr solution (unknown) Mixer x5 wt % HBr (unknown) m2 kg/hr solution (unknown) V2 L/hr solution (unknown) wt% water (unknown) X3 = 50.0 wt% HBr x4 wt% water (unknown) How many unknowns are in this process?
