if the HCl is 0.1 M standard solution and you must add 30 mL to reach the end point, what is the molarity of the NaOH?

A. 0.1

**B 0.2**

C. 0.3

D 1

E 2

I tried using m1v1=m2v2 but I got stuck, can someone solve this please? thanks

Is there any information given about the volume of NaOH in the conical flask for the titration?

unfortunately no thats why i couldnt do m1v1

Oh! I got a very similar question and it gave the value as 15 mL which gives 0.2 as the molarity:

m1v1=m2v2

30 x 0.1=M x 15

x=0.2

Maybe there was a typo? But your technique is right!

goof to know! i think there was a mistake yeah
