Density = Mass/Volume => V = M/D
So Vol = 25.8/2.56 = 10.1 units (approx) of the volume in which the density was expressed.
Density=Mass/Volume You need also to know the volume !
If you know the density and the volume, you can calculate the mass. This is becausedensity = mass/volume.
Density can also be considered volume in this question meaning that the object will sink.
You need also the mass of the material: volume = mass/density. After you measure the mass of the object, then divide by the density, to find volume.
The shape of an object is not enough to calculate its density. You also need its mass and then Density = Mass/Volume.
Density=Mass/Volume. So D=3/2. Which is also 1.5. To the density of the object is 1.5 g/ml
Density is mass divided by volume, so if mass increases but volume stays the same, then density also increases.
Density is the mass per unit volume of a substance. If you can take a unit volume, (1cm3) of a material, the measured mass is it's density. Also, if you cannot separate out a unit volume, you can measure the volume of an object by immersing it in a liquid and measuring the volume of the liquid displaced by the object. Then measure the mass of that object. Density (Mass / Volume) When mass is measured in kg, and volume in metres, Units of density is kg/m3 In Chemistry, however, density is measured in grams per cubic centimetre, g/cm3
You don't know the density if you only know the mass. You can figure it out if you also know the object's volume.
Not enough information. You would also have to know either the volume, or the density, of the object.
Assuming mass does not also increase, then density decreases if volume increases. For example, let's say Mass= 100 and Volume= 50 Density would = 2 Now, lets increase the volume. Mass would still = 100, and let's increase the volume to 75. Density would then equal 1.333... 2 is greater than 1.333.... so yes, density decreases as volume increases.
They are correlated by volume weight/volume = density. For example, in a metal coin, the weight might not be much, but the volume is also very low, so it turns out that the density is high. Gases have almost no weight in a lot of volume, so their density is low.
