Actually, BOTH are used. You can define density as mass divided by volume (or mass per unit volume).
density = mass/volume
The object's density = (its mass) divided by (its volume)
The formula for calculating density is as follows: density = mass/volume. Simply put, if you divide an object's mass by its volume, you will find its density. Density is the mass of an object per unit volume.
The definition of density is: Density = (Mass) divided by (Volume).A simple algebraic operation rearranges this definition to give: Mass = (Density) times (Volume)
density=mass/volume d=m/v
Weight = (density) times (volume)The definition of density is mass/volume .Now [ weight = mass x gravity ], so [ mass = weight/gravity ], and [ density = weight/gravity x volume ] .So Weight = (density) x (volume) x (gravity)
The formula for calculating mass is mass = density x volume. This formula relates the mass of an object to its density (amount of matter in a given volume) and volume (amount of space an object occupies).
Andrew made a mistake in calculating density by not properly measuring the volume of the object. Density is calculated by dividing the mass of an object by its volume, and if the volume is incorrect, it will lead to an inaccurate density value.
Air density can be determined by measuring the mass of a known volume of air and then calculating the density using the formula: density mass/volume. This can be done using instruments such as a balance and a container of known volume.
Mass = Density x Volume Density = Mass/Volume Volume = Mass/Density
There is no direct relationship between how much mass an object has and it's volume. That is, mass plays no part in calculating the volume, and volume plays not part in determining mass. However, they are related by the equation to calculate the density. Density=Mass/Volume.
To determine the density of a mineral, you need to know its mass and volume. The mass of the mineral can be measured using a balance, while the volume can be determined using displacement method or by measuring its dimensions and calculating the volume. Density is calculated by dividing the mass of the mineral by its volume.
