The correct units for mass are kilograms (kg) and for density are kilograms per cubic meter (kg/m^3).
Density is calculated by dividing the mass of an object by its volume. The formula for density is: Density = Mass / Volume. Make sure to use units that are consistent, such as grams for mass and cubic centimeters for volume, to get the correct density value.
The volume of the substance can be calculated using the formula: volume = mass/density. In this case, the volume would be 80/40 = 2 cubic units.
Density is mass divided by volume. In this case, density is 6 divided by 12, which equals 0.5. This means the density is 0.5 units per whatever units you are using for mass and volume.
Volume is the space occupied by an object or substance. When working with density, volume is important because density is defined as mass per unit volume. By knowing the volume of a substance and its mass, you can calculate its density.
Density is the quotient of two physical properties: mass and volume. If Mass is needed, given Density then the Volume needs to be found in order to complete the equation: mass = density times volume in compatible units. For SI units, the units would be Density = kilograms per cubic meters Mass = kilograms Volume = cubic meters or try this To find mass divid the density
