The final concentration of the solution after adding water is HCl is 1.25M.
The solution of 25ml of 22M HCl is diluted to 440ml.
So, as we know,
Moles = molarity x volume
So, he moles of HCl are,
Moles = 22 x 25
Moles of HCl are 550 mole.
Even after diluting, the mole will not change, so,
Final concentration after adding water,
Concentration = 550/440
Concentration = 1.25M.
So, the final concentration of the HCl solution is 1.25M.
