Molarity of Concentrated solution - (Dec/27/2010 )

How to determine the molairty of the concentrated solution?????
for example molarity of the HCl (that is 37.5 %), what is its molarity???

This will always be approximate, without titration to set a final concentration, but roughly:

Thanks, This one I know that HCl has a 12 M but I did not get the formula, cuz I have some other compunds like concentrated mustard oil but I dont know how to measure its concentration. For HCl I find this formula but I did not get that

((37.5/100)(1000)(1.189))/36.46 = 12.2M

regards
