When you compare masses of the same volume of different substances you are doing what?
Comparing density
How could you tell the difference in density between the same size samples of quartz and galena?
By deviding the mass by its volume.
How can you obtain an objects volume if you know its density and its mass?
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.
What is the ratio of mass and volume?
The ratio of mass to volume is called density.
Does the volume of water change the density of water?
Density = mass / volume. So if the volume changes, the density will obviously also change.
How Mass and volume can affect the density of the volume?
The definition of density is mass per unit volume. For any object or sample of a substance, it can be calculated as (mass) divided by (volume). If two objects or samples with the same volume have different masses, the one with the greater mass has greater density. If two objects or samples with the same mass have different volumes, the one with the greater volume has smaller density.
How is it possible for objects to have the same volume but different masses?
Their masses are different. (Mass = density * volume)
Is density the volume of equal masses of substances?
yes
What is the density of a sample of nickel with a mass of 3.1 g and volume of 0.35 mL?
The nickel's density is about 8.91 g/cm3
Why do two samples with the same substance with the same volume HAVE to have the same mass?
Because they are of the same substance they have the same density density = mass/volume
How would the densities of the sphere and cube have compared if the masses of the cube and sphere had been the same but the volume of the cube had been greater?
Density = Mass/Volume, whatever the shape. So, if the masses are the same, the density is greater when the volume id smaller. Thus the sphere, with the smaller volume has the greater density.
What is the density of a nickel if it were sawed in half?
It is unchanged. The density is the mass divided by the volume, and as both of these numbers are halved the density does not change.
When you compare masses of the same volume of different substances you are doing what?
Comparing density
How can you describe the relationship between mass and volume for these samples?
Relative densities (specific gravity) density of sample = mass / volume
What is the relationship between mass and density when the volume of each liquid is the same?
For two liquids of the same volume, the liquid with a higher density will have greater mass. Similarly, the liquid with a greater mass has a higher density. This is only true for samples of equal volume, however.
What is the difference volume and mass?
mass is weight. volume accounts for size. density of items change therefore masses are not the same as volumes
Can two objects have the same volume but not the same density?
no density equals mass divided by volume. if both solids have a mass of 100 grams (for example) one has a volume of 100 mL (or centimeters cubed), it's density is 1 g/mL if the other has a volume of only 50 mL it's density is 2 g/mL
