Elena weighed out 5 newtons of salt. She dissolved the salt in 250 newtons of water. A diagram of her procedure is shown below. How did the addition of salt affect the final weight and volume of the mixture? A. The volume of the mixture increased by the same volume of salt that was added, and the weight of the mixture decreased by the same weight of salt that was added. B. The weight of the mixture increased by the exact weight of the salt added, but the volume didn't change. C. Neither the volume nor the weight of the mixture changed when the salt was added. D. The volume of the mixture increased by the same volume of salt that was added, and the weight of the mixture increased by the same weight of salt that was added.
