According to your own question, the density is 2.55 grams per cm3. So why ask?
The density of the marble would be determined by dividing the marble's mass (12.5 g) by its volume (5ml), which would give you 2.5g/ml.
The density is 2,43 g/cm3.
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).
The ratio of mass to volume is called density.
You just need to rework the density formula: D = M / V, where D is density, M is mass, and V is volume. So all you need to do is put in the Density and Mass and solve for V: D = M / V D * V = M V = M / D And so our volume becomes Mass divided by Density.
The density of the marble is about 4.94 g/cm3
What do you want to measure about the marble? Its diameter, radius, circumference, volume, mass, density...?
Since density is mass per unit volume, the density is the same.
The density of the marble would be determined by dividing the marble's mass (12.5 g) by its volume (5ml), which would give you 2.5g/ml.

Density = Mass/Volume = 3.050/[4/3*pi*r3] = 2.91 grams/cm3
The density is 2,43 g/cm3.
This density is 4,07 g/cm3.
The density is 2,43 g/cm3.
You are supposed to divide the mass by the volume.
