The orange liquid's molecules were very close together but not as close as the blue liquid's molecules were. The green solution´s molecules were not as close together as the orange or blue ones were. The yellow solution´s molecules were more spread out than the green´s solution. The red liquid´s particles were much more spread out than any other solution. Therefore, the red mixture is much less dense than any other…
