Answer: The volume of NaOH is 30 mL.
Explanation:
To calculate the concentration of acid, we use the equation given y neutralization reaction:
[tex]n_1M_1V_1=n_2M_2V_2[/tex]
where,
[tex]n_1,M_1\text{ and }V_1[/tex] are the n-factor, molarity and volume of acid which is HCl
[tex]n_2,M_2\text{ and }V_2[/tex] are the n-factor, molarity and volume of base which is NaOH.
We are given:
[tex]n_1=1\\M_1=0.1M\\V_1=30mL\\n_2=1\\M_2=0.1M\\V_2=?mL[/tex]
Putting values in above equation, we get:
[tex]1\times 0.1\times 30=1\times 0.1\times V_2\\\\V_2=30mL[/tex]
Hence, the volume of NaOH is 30 mL.
