An acetic acid aqueous solution contains 22% by mass acetic acid? Which of the following statements is correct?
A)1 mL of this solution contains 22 g of acetic acid
B)1 L of this solution has a mass of 22 g
C)100 g of this solution contains 22 g of acetic acid
D)1 L of this solution contains 22 mL of acetic acid
E)the density of this solution is 2.2 g/mL

If the solution contains 22% acetic acid by mass, then in 100g of the solution there will be 22g of acetic acid. A) is incorrect because 1 mL of the solution will weigh 1.22 g (not 22 g) since it is not a pure acetic acid solution. B) is incorrect because 1 L of the solution will have a mass of more than 22 g since water has a density of 1 g/mL. D) is incorrect because the volume of the solution is not equal to the volume of the acetic acid. E) there is not enough information to determine the density of the solution.
