I'm sooooo lost.

If 12.57 mL of NaOH solution is needed to reach the endpoint in a titrating 10 mL of a 0.3175 M HCl solution, what is the molarity of Sodium Hydroxide?

I've gotten pretty far but am lost as to where I get my mole to mole ratio and stuff.

N1VI = N2V2
FOR HCL MOLARITY=normality coz basicity is 1
0.3175x10=N212.57
N2=0.3175x10 divided by 12.57
N2=0.2526
hence m=0.2526
i hope i helped
