The mass formula states that mass (m) is calculated as the product of an object’s density (ρ) and its volume (v). Mathematically, the formula for mass is expressed as m = ρ × v. This formula enables the calculation of the mass of an object based on its density and volume.
Practice problems
Problem #1
Calculate the mass of a steel object if the density of steel is 8050 kg/m3 and the volume of the object is 0.012 m3.
Solution
Given data:
- Mass of the object, m = ?
- Density of steel, ρ = 8050 kg/m3
- Volume of the object, v = 0.012 m3
Applying the formula:
- m = ρ × v
- m = 8050 × 0.012
- m = 96.6 kg
Therefore, the mass of a steel object is 96.6 kg.
Problem #2
If the density of a diamond is 3510 kg/m3 and the volume of the diamond is 0.005 m3, then calculate the mass of the diamond.
Solution
Given data:
- Density of a diamond, ρ = 3510 kg/m3
- Volume of a diamond, v = 0.005 m3
- Mass of a diamond, m = ?
Applying the formula:
- m = ρ × v
- m = 3510 × 0.005
- m = 17.55 kg
Therefore, the mass of a diamond is 17.55 kg.
Problem #3
The density of silver is 10497 kg/m3 and the volume of the silver object is 0.008 m3. Calculate the mass of the silver object.
Solution
Given data:
- Density of silver, ρ = 10497 kg/m3
- Volume of the object, v = 0.008 m3
- Mass of the object, m = ?
Applying the formula:
- m = ρ × v
- m = 10497 × 0.008
- m = 83.97 kg
Therefore, the mass of a silver is 83.97 kg.
Problem #4
Find the mass of a block of ice with a density of 917 kg/m3 and a volume of 0.007 m3.
Solution
Given data:
- Mass of ice block, m = ?
- Density of block, ρ = 917 kg/m3
- Volume of block, v = 0.007 m3
Applying the formula:
- m = ρ × v
- m = 917 × 0.007
- m = 6.41 kg
Therefore, the mass of an ice block is 6.41 kg.
