The following cylinder contains three liquids that do not mix with one another: water (density = 1.0 g/mL), vegetable oil (density = 0.93 g/mL), and mercury (density = 13.5 g/mL). Which liquid is which?

Hi everyone today. We have a question telling us that two types of sand are to be separated using the difference in density. In the liquid sand A has a density of 1.21 g per centimeters cubed, and sand B has a density of 2.93 g per centimeter cubed. The two sand samples will be placed in a container and mixed well with the liquid. Upon settling, the denser materials will be at the bottom and the less dense material will float to the top. Given the following un reactive liquids in their densities, identify which one of them would be a good option for the separation. So for the separation we need a liquid that is denser than a and less dense than b. So if we look at liquid a. that works Liquid B 1.51 that works Liquid C 0 .95. That will not work because it is less dense than A. And d. That also works. So our answers here are A. B. Nd. Thank you for watching. Bye.
