chemistry-molarity

Say I have 50 mL of bromocresol green indicator. This solution has 80mg/L. the molar mass is 698 g/mol.

Then say I took 10 mL of that solution and dilute it with .4 M HCI.

I want to find the concentration/molarity of bromocresol green.
This is what I have attempted to do:

10ml(1L/1000 ml)(1 mol/698g)(1g/1000mg)(80mg/mol)(50mL)(1L/1000 mL)
= 5.73*10^-5 M

Is that even remotely correct?
