# Simple molarity calculation?

Can somebody check my math?

I'm trying to figure out the molar concentration of bromophenol blue. The total volume of the solution is 10 mL, with 0.1 mL of 3 x 10^-4 M bromophenol blue.

From my calculations, I got 3 x 10^6 M. Is this correct?

Update:
Buddy, you didn't understand the question. If I'm making a 10 mL solution, using 0.1 mL of a 3 x 10^-4 molar solution of BPB, the molarity of the 10 mL solution isn't 3 x 10^-4.
