WebProblem #28: Given 8.00 g of HBr calculate the volume (mL) of a 48.0% (w/w) solution. (MW HBr: 80.9119 g/mol, density: 1.49 g/mL). Then, calculate the molarity. Solution: 8.00 g divided by 0.48 = 16.6667 g --- total mass of the solution in which the HBr is 48% by mass 16.6667 g divided by 1.49 g/mL = 11.18568 mL to three sig figs, the volume of ... WebThe brominating mixture is made by dissolving 13 mL of bromine in enough 48% HBr aqueous solution to make a total of 100 mL of solution. What is the molarity of bromine in this solution? (density of bromine 3.10 g/mL. Note that you do not need 48% HBr at all in your calculation because it is only a solvent).
