0.7 mol of H⁺ ions are present in 2.8 l of 0.25 m hydrobromic acid solution.

Hydrobromic acid is a strong acid, we can assume that all acid molecules dissociate completely to yield H+ ions and dissociated anion.

The equation for the dissociation of HBr :

                             Hbr (s) →  H⁺ (aq)  +  Br⁻ (aq)

moles H⁺ = ([tex]2800ml[/tex]) ( [tex]\frac{1L}{1000ML}[/tex])  ([tex]\frac{0.25 mol Hbr}{L}[/tex]) ( [tex]\frac{1 mol H}{1 mol Hbr}[/tex])

               = 0.7 mol

Therefore, 0.7 mol of H⁺ ions is present.
