Determine the concentration of an HBr solution if a 45.00 mL aliquot of the solution yields 0.5555 g AgBr when added to a soluti

amid [387]

Molecular weight of AgBr = 187.7
moles of Ag = $\frac{0.5555}{187.7} = 2.96 x 10^{-3}$
moles of Br = moles of Ag = 2.96 x 10⁻³ mol
concentration of HBr (Molarity) = conc. of Br (strong acid) = $\frac{2.96 x 10^{-3} }{45 x 10^{-3} } = 0.0658 mol/l$
