The simplest and still pretty accurate answer would be based on the following things. The concentrated HCl means it is 12M. You can simpy use M1*V1=M2*V2 formula to calculate what You are looking for. In this case You do not have to worry switching from normal solution to molarity since 1M is = to 1 N for HCl.
Using M1*V1=M2*V2, where M stands for molarity and V for volume:
12M *X(unknown volume) ml (in mililiters) = 1 N (or 1M) * 1000 ml
1000 ml*M /12 M = 83.33(3) ml
