How to Calculate Mass Using Weight, Density, or Moles?
What is Mass Calculator?
The Mass Calculator is a free online tool that helps you quickly determine the mass of an object or substance using standard formulas from physics and chemistry. Whether you have information about density and volume, weight, or the number of moles and molar mass, this mass calculator makes the process simple and accurate.
Mass is a fundamental property of matter, used in mathematics, scientific studies, chemical equations, and real-world applications like body mass or shipping weights. This tool supports multiple unit systems and applications for hassle-free calculations in one place.
Formula or Logic Behind Mass Calculator
The mass of an object can be calculated using several formulas depending on the information you have:
1. From Density & Volume: Mass = Density × Volume (m = ρ × V)
2. From Weight: Mass = Weight / Gravity (m = W / g)
3. From Number of Moles (Chemistry): Mass = Number of moles × Molar mass (m = n × M)
The calculator automatically handles the unit conversions for you. For example, it can convert density from g/cm³ to kg/m³ or volume from mL to m³, ensuring your answer is always correct.
Example Mass Calculation Table
Scenario | Input Values | Calculation | Result |
---|---|---|---|
Physics | Density = 2 g/cm³, Volume = 1000 cm³ | Mass = 2 × 1000 = 2000 g | 2 kg |
Labs | Weight = 49 N, Gravity = 9.8 m/s² | Mass = 49 / 9.8 | 5 kg |
Chemistry | Moles = 0.5, Molar mass = 18 g/mol | Mass = 0.5 × 18 | 9 g |
Everyday | Density = 1 g/cm³, Volume = 2 L | Mass = 1 × 2000 = 2000 g | 2 kg |
Steps to Use the Mass Calculator
