A HCL Aqueous solution is 7% (volume by volume) 7ML HCl is present in 100ML solution?

1 answer

Yes, that is correct.

To calculate the percentage of a solution by volume, we divide the volume of the solute by the volume of the solution, and then multiply by 100:

% = (volume of solute / volume of solution) x 100

In this case, we have 7 mL of HCl in 100 mL of solution, so:

% = (7 mL / 100 mL) x 100
% = 7%

Therefore, the HCL aqueous solution is 7% (volume by volume).
