Answer:
[tex]720\ \text{mL}[/tex]
Explanation:
M = Molarity of NaOH = 0.25 M = 0.25 mol/L
n = Number of moles of NaOH = 0.18 moles
Volume of solution is given by
[tex]V=\dfrac{n}{M}[/tex]
[tex]\Rightarrow V=\dfrac{0.18}{0.25}[/tex]
[tex]\Rightarrow V=0.72\ \text{L}\times 10^3=720\ \text{mL}[/tex]
The volume of NaOH in the solution is [tex]720\ \text{mL}[/tex].
