Question

Jay had two clear liquids in bottles. The mass of one liquid was 10.2 grams and the other was 7.6 grams. When he mixed them, a yellow solid formed and settled to the bottom of the bottle. He predicted that the liquid plus the solid would have more mass, so he put the bottle on a scale. The mass was 17.8 grams. Why did the mass not change?

Answer 1

The reason the mass did not change because he did not add anything to the mixture accept the two liquids and its not possble to change the mass/ weight of any certain weighted item like the which is heavier the 1 pound of feathers or the 1 pound of bricks the only things is that the brick has more density so there for neither one is heavier than the other because the are both a pound
