Which combination of units expresses density?
The mass doesn't change; just the numbers.
No, the mass is the same. Only the numbers are different.
kg
The kilogram.
The units for the volume if you are measuring any liquid or solid is metre^3/cm^3 as density = mass/volume. The units for mass is grams
12.3 units of mass per unit of volume.12.3 units of mass per unit of volume.12.3 units of mass per unit of volume.12.3 units of mass per unit of volume.
Divide the mass by the volume and express the answer in terms of "units of mass per units of volume" - in this case, grams per cm^3..
Which combination of units expresses density?
mass, length and time are the basic measurement units
The answer depends on the units used for the change in mass. Since there are no units, there can be no meaningful answer.
Yes. You can find the density of a meterial if you have the mass and volume. You can use the formula D=mass/volume. The units for mass is grams and the units for volume are cm^3
