Answer:

Step-by-step explanation:

Here, we want to get the volume of barium hydroxide that must be used

From the balanced equation of reaction, 1 mole of barium hydroxide produced 2 moles of water

x moles of barium hydroxide will produce 5.5 moles of water

To get the value of x, we have it that:

$\begin{gathered} 1\text{ - 2} \\ x\text{ - 5.5} \\ \\ 2* x\text{ = 5.5 }^*1 \\ x\text{ = }(5.5)/(2) \\ \\ x\text{ =2.75 moles} \end{gathered}$

Mathematically:

$\begin{gathered} number\text{ of moles = volume }*\text{ molarity} \\ volume\text{ = }\frac{number\text{ of moles }}{molarity} \end{gathered}$

From the question, the molaity is 0.125 M

Thus, we have the number of moles as:
