PLEASE HELP WHICH ONE IS IT AND CAN YOU EXPLAN HOW YOU GOT THE ANSWERS TY!!! In a titration, a 20 mL sample of NaOH(aq) was neutralized by 14.9 mL of 0.13 mol/L
H2SO4(aq). The concentration of the base is
A)8.7 mol/L
B)10.048 mol/L
C)0.19 mol/L
D)0.35 mol/L
/L

C)0.19 mol/L .

Explanation:

Hello!

In this case, since the chemical reaction between sodium hydroxide and sulfuric acid is:

Whereas a 1:2 mole ratio is seen between the acid and the base, we can write:

In such a way, we solve for the concentration of base and plug in to obtain:

Thus, the answer is C)0.19 mol/L
