Understanding how to calculate the mass of an object is crucial for a variety of scientific and engineering applications. Mass, distinct from weight, is a measure of the amount of matter in an object. It remains constant irrespective of location, unlike weight, which can vary with gravity.
This concept is foundational in fields ranging from physics to chemistry, where precise mass measurement is essential. Whether you're calculating mass for academic purposes, or real-world applications like balance adjustments in engineering projects, knowing the exact process is vital.
We'll delve into the detailed steps on how to compute an object's mass, including its formulae and the necessary considerations. Additionally, we'll explore how Sourcetable can simplify these calculations using its AI-powered spreadsheet assistant.

Calculating the mass of an object is a fundamental task in various scientific and industrial applications. Mass can be determined through different methods depending on the physical properties and available tools. Understanding the correct technique and formula is essential for accurate measurement.
One common method involves using the object's density and volume. Initially, determine the density ρ (typically in kg/m3) and measure the volume V (in m3). The mass m can then be calculated using the formula m = ρV.
Another approach is through Newton's second law where force F and acceleration a are known. Using the formula m = F/a, calculate mass by dividing the force exerted on the object by the acceleration.
For chemical substances, mass can also be calculated via molar mass. Determine the atomic mass for each element in the substance, sum them to find the total atomic mass units (amu), and convert it to grams using 1 g/mol. This method is particularly useful in chemistry for finding the mass of specific number of molecules.
Direct measurement can be achieved using different types of balances. A triple-beam balance or double-pan balance can provide gravitational mass measurements, best suited for laboratory settings. For dynamic environments, an inertial balance measures mass by analyzing the object's motion, applicable in any gravitational context.
Choose the most suitable method based on the object’s characteristics and the measurement environment. For accuracy, follow the proper steps for each method and use calibrated instruments. This ensures precise and reliable mass calculations.
To determine the mass of an object, use the formula m = ρV, where m represents mass, ρ indicates density, and V signifies volume. Essential units are kg for mass, kg/m3 or g/cm3 for the density of solids, and kg/L or g/mL for the density of liquids. This approach necessitates known values for density and volume.
First, look up or measure the object's density. You can find density values in textbooks or reliable online databases. Next, measure the object's volume, which is the space it occupies. Solid volumes are typically measured in cubic meters (m3) or cubic centimeters (cm3), and liquid volumes in liters (L) or milliliters (mL). Finally, multiply the density by the volume to find the mass.
If density and volume are not available, mass can alternatively be derived through gravitational or inertial methods. Gravitational mass, reacting to Earth’s gravity, can be measured using a scale. Inertial mass, indicating resistance to movement, can be measured by applying and measuring force against the object.
For precise measurements, a balance scale is often used. When using a triple beam balance, align the beams and read the scales to the nearest half tick mark. If dealing with solutions, add the mass of the solute to that of the solvent to find total mass. This is calculated by the formula m = ρV.
To calculate the mass of a cube with a volume of 2 m³ and a density of 500 kg/m³, use the formula: Mass = Density × Volume. Thus, the mass is 1000 kg.
The mass of an object can also be determined by its weight. For an object weighing 980 N on Earth, where gravitational acceleration is approximately 9.8 m/s², mass is calculated as Mass = Weight ÷ Acceleration due to Gravity. This gives a mass of 100 kg.
For a balance scale, if an object balances out with a known mass of 5 kg on the other side, the object’s mass is also 5 kg.
If an object submerged in water displaces 200 liters of water, with 1 liter of water weighing approximately 1 kg, then using the formula Mass = Displaced Water Volume × Density of Water, the object's mass is 200 kg.
Calculating the molar mass of a substance, say water (H2O): with hydrogen's atomic mass around 1 u and oxygen's around 16 u, the molar mass of water is 1(2) + 16 = 18 u.
