Answer:
A
Explanation:
Mass is a measure of the amount of matter in an object.
The pH of the solution is 1.38.
Mass of HCl = 614 mg = 0.614 g
Moles of HCl = 0.614g / 36.5 gmol⁻¹
Concentration of HCl :
Concentration= moles/volume of solution in liters
On adding 0.01682 moles to 400 mL of water that 0.4 L of water.
[HCl]=0.01682 mol/0.4 L= 0.04205 M
HCl (s) + H₂O (l) → H₃O⁺ (aq) +Cl⁻
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:
1x0.04205 M= 0.04205 mol/L of hydronium ions.
[H₃O⁺]= 0.04205 M
pH= -log[H₃O⁺]
pH= -log[0.04205 M]
= 1.38
The pH of the solution is 1.38.
