    151.056 g A. Acid pure.

    Explanation:

    First, we going to change mL to grams using the density:

    1.049 g / mL means that 1 mL of solution weight 1.049 g:

    360 mL x (1.049 g / 1 mL) = 377.64 g Solution.

    Then. we have to find the amount of pure acetic acid we have.

    A solution at 40 % means that for 100 g of the solution just 40 g is pure acetic acid:

    377.64 g solution x (40 g acetic acid/100 g solution) = 151.056 g A. Acid pure.
