Answer:
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.
