Question

Map c Sapling Learning macmillan learning Two aqueous hydrogen bromide solutions containing 1.00wt% HBr(SG = 1.0041) and 30.0 wt% HBr (SG = 1.2552) are mixed to form a 2.86 molar HBr solution (SG-1.1557) What feed rate of the 30.0 wt% HBr solution would be required to produce 1.00 x 103 kg/hr of product? Number 522.3 L/ hr What is the feed ratio of liters of 1.00 wt% HBr solution to liters of 30.0 wt% HBr solution? Incorrect. You have found the correct volumetric flow rate of 30.0 wt% HBr solution. Check that you have found the correct mass flow rate for the 1.00 wt% solution, and converted that mass flow rate to a volumetric flow rate properly. Have you used the appropriate specific gravity? Number 522.3

Explanation / Answer

Volumetric flow rate of 30 wt% HBr = 522.3 L/hr

Mass flow rate of 30 wt% HBr

= 522.3 L/hr x 1255.2 kg/m3 x 1m3/1000L

= 655.590 kg/hr

Overall mass balance

Mass of 30 wt% HBr + Mass of 1 wt% HBr = mass of product

655.590 + Mass of 1 wt% HBr = 1000

Mass of 1 wt% HBr = 344.41 kg/hr

Volumetric flow rate of 1 wt% HBr

= 344.41 kg/hr / 1.0041 kg/L

= 343 L/hr

Feed ratio of litres of 1 wt% HBr to 30 wt% HBr

= 343/522.3

= 0.6567
