Answer:
[tex]M_{acid}=0.114M[/tex]
Explanation:
Hello there!
In this case, according to the given information, it is possible for us to firstly write the chemical equation whereby sulfuric acid is titrated with sodium hydroxide:
[tex]H_2SO_4+2NaOH\rightarrow Na_2SO_4+2H_2O[/tex]
Whereas the mole ratio of acid to base is 1:2 and therefore, the relationship between the volumes and molarities is:
[tex]2M_{acid}V_{acid}=M_{base}V_{base}[/tex]
Thus, we solve for the required molar concentration of the acid as shown below:
[tex]M_{acid}=\frac{M_{base}V_{base}}{2V_{acid}} \\\\M_{acid}=\frac{0.100M*45.65mL}{2*20.00mL}\\\\M_{acid}=0.114M[/tex]
Regards!
