Answer:
The volume of NaOH solution is 14.8 mL.
Explanation:
the chemical reaction between phosphric acid and sodium hydroxide is as follows.
[tex]H_{3}PO_{4}+3NaOH\rightarrow Na_{3}PO_{4}+3H_{2}O[/tex]
[tex]Moles\,of\,H_{3}PO_{4}= \frac{Mass}{Molarmass\,of\,H_{3}PO_{4}}[/tex]
[tex]= \frac{0.0966}{97.995}=0.00098576mol[/tex]
[tex]Moles\,of\,NaOH=3\times moles\,of\,phosphricacid[/tex]
[tex]Moles\,of\,NaOH=3\times 0.00098576= 0.0029573mol[/tex]
[tex]Volume\,of\,NaOH=\frac{Mole}{Concentration}=\frac{0.0029573}{0.2000}=0.0148L=14.8ml[/tex]
Therefore, The volume of NaOH solution is 14.8 mL.
