A quality-control technician is testing the concentration of muriatic acid (hydrochloric acid) to check that the concentration is within certain limits. Calculate the concentration of the hydrochloric acid if a 15.0-mL sample is titrated with standard sodium carbonate solution. The titration required 10.00 mL of 0.350 mol/L sodium carbonate to neutralize the acid.
