The answer is 6 moles.

Since the mole ratio of ch4 to o is 1:2, and we have 3 moles of ch4, we can just multiple 3 moles by 2 and get 6 moles

How many moles of h+ ions are present in 2.8 l of 0.25 m hydrobromic acid solution?
Romashka [77]

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.

<h3>The equation for the dissociation of HBr :</h3>

                             Hbr <em>(s) →  </em>H⁺ <em>(aq)  </em>+  Br⁻<em> (aq)</em>

<em></em>

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

               = 0.7 mol

Therefore, 0.7 mol of H⁺ ions is present.
