Determine how many moles of ba(oh)2 are required to completely neutralize 0.425 mole of hc2h3o2.

Answer : The number of moles of required are, 0.2125 moles.

Explanation : Given,

Moles of = 0.425 mole

The balanced chemical reaction will be:

From the balanced chemical reaction we conclude that,

As, 2 moles of completely neutralize by 1 mole of

So, 0.425 moles of completely neutralize by mole of

Therefore, the number of moles of required are, 0.2125 moles.
