One among the following is an incorrect statement-

When 5.0 gram of BaCl₂ is dissolved in water to have 10⁶ gram of solution. The concentration of solu

0.2 mole of HCl and 0.1 mole of CaCl₂ were dissolved in water to have 500 mL of solution, the molari

25 mL of 3 M HCl were added to 75 mL of 0.05 M HCl. The molarity of HCl in the resulting solution is
