The concentration of commercial HCl is considered to be 12 M. I think it is more like 11.6 M but use either number you wish depending upon your definition of concentration of HCl. Then
mLa x Ma = mLb x Mb
mLa x 12 = 250 x 0.1
Solve for mLa. Than pipet that amount of concentration HCl into a 250 mL volumetric flask, add some distilled water to the flask, swirl somewhat, add distilled water to the mark on the volumetric flask, stopper, mix thoroughly, label.
