Hydrobromic acid molar mass g/mol
Hydrobromic acid is a strong acid formed by dissolving the diatomic molecule hydrogen bromide (HBr) in water. "Constant boiling" hydrobromic acid is an aqueous solution that distills at 124.3 °C (255.7 °F) and contains 47.6% HBr by mass, which is 8.77 mol/L. Hydrobromic acid has a pKa of −9, making it a stronger acid than hydrochloric acid, but not as strong as hydroiodic acid. Hydrobromic acid is one of the strongest mineral acids known.

WebIt is a hydrogen halide consisting of hydrogen and bromine. A colorless gas, it dissolves in water, forming hydrobromic acid, which is saturated at 68.85% HBr by weight at room temperature. HCI = Hydrochloric acid. hydrogen chloride ... In this case, the molar mass of HBr is 1 g/mol + 80 g/mol = 81 g/mol. So, 305 g HBr / 81 g/mol = 3.75 mol HBr. WebWhen the hydrobromic acid concentration was increased from 0.5 mol·L-1 to 1 mol·L-1, the energy efficiency and the voltage efficiency increased by 27.9% at the current density of 200 mA·cm-2. In the charge process, as the hydrogen pressure was reduced, the battery charging performance improved, but severe membrane acid permeability was observed.
