    The concentration of HCl in the mixture is 1L of 50% HCl

    Step-by-step explanation:

    Here, we want to know the percentage of HCl present which refers to the its concentration.

    Firstly, the total volume we have is 0.375 + 0.625 = 1 L

    we can calculate the percentage as follows;

    The percentage of the 25% present is 37.5%

    while the percentage of the 75% present is 62.5%

    When we say the percentage present, we are referring to the amounts of the total liters which is 1 present.

    So the concentration of the final mixture will be;

    (37.5% of 25) + (62.5% of 65)

    = 9.375% + 40.625%

    Adding both gives = 50%

    So the concentration we have is 1L of 50% HCl
