Achemist dissolves 614. mg of pure hydrochloric acid in enough water to make up 400 ml of solution. calculate the ph of the solution. round your answer to 3 significant decimal places. x 5 ? 1 don't know suomi

The pH of the solution is 1.38.

Explanation:

Mass of HCl = 614 mg = 0.614 g

Moles of HCl =

Concentration of HCl :

On adding 0.01682 moles to 400 mL of water that 0.4 L of water.

1 mole of HCl gives 1 mole of hydronium ion and 1 mole of chloride ions in an aqueous solution.

Then 0.04205 mol/L of HCl will give:

of hydronium ions.

The pH of the solution is 1.38.
