Two aqueous hydrogen bromide solutions containing 12.0 wt% hbr (sg = 1.1377) and 40.0 wt% hbr (sg = 1.3736) are mixed to form a 3.90 molar hbr solution (sg = 1.1234). what feed rate of the 40.0 wt% hbr solution would be required to produce 1.00 x 108kg/hr of product? number 01/ what is the feed ratio of liters of 12.0 wt% hbr solution to liters of 40.0 wt% hbr solution? number previous give up & view solution check answer next exit hint draw and label the flow diagram for this process. find the mass percent of hbr in the product solution. molarity is moles solute per liter of solution. use the molar mass of hbr (80.9119 g/mol) and the specific gravity of the solution to convert the given molarity to a mass percent of hbr.
