A) 417 mL of 36% acetic acid in 583 mL of distilled water
B) 417 g of 36% acetic acid in 583 g of distilled water
C) 360 mL of 36% acetic acid in 640 mL of distilled water
D) 360 g of 36% acetic acid in 640 g of distilled water
E) 150 g of 36% acetic acid in 850 g of distilled water

To achieve a 15.0% (w/w) acetic acid solution from a 36.0% solution, the mass of the acetic acid in the final solution must be 15% of the total mass (1.00 kg). Option B correctly maintains the mass proportions, using 417 g of the 36% acetic acid solution to achieve the desired concentration when mixed with 583 g of water, totaling 1.00 kg of the final solution.
