How could you determine the densities of two different fluids without mixing them together?

Answer 1

1) determine the density of the first fluid

2) determine the density of the second fluid

step 1) and step 2) are easy. just measure the volume and the mass and use the formula: "density = mass/volume"

you can also...

~put the liquids in beakers (same amount in both)

~get a little marble

~drop the marble in one of the beakers

~use a timer to time how long it takes the marble to reach the bottom.

~take the marble out or if you have another marble use that

~drop the marble into the second fluid

~time how long it takes to reach the bottom

~the fluid with the less time should be the one that is denser

( you don't have to use marbles, you can use any other two object that are and weight the same).

Answer 2

One way is to use a graduated cylinder to measure the volume of each fluid. Then, using a balance to determine the mass of each fluid, you can calculate the density by dividing the mass by the volume. Another method involves using a hydrometer, which measures the specific gravity of each fluid and allows for the determination of their densities without mixing.
