How to Find Mass From Volume

Although the relationship between mass and volume is interconnected by a scientific equation, one must understand how to find the density and volume before determining the mass of an object. The mass refers to the weight of a given object with respect to the gravitational pull, while volume refers to the amount of space a three-dimensional object contains. By knowing the volume and density of an object, you can solve for mass using the mass equation.

Beaker
Water
Scale

Instructions

- 1
  Find the volume of the object by first placing the object in a beaker full of water and observing the displacement in the water. Write down the amount of water before and after the object was placed into the beaker. The value of the water displacement is the volume of the object.
- 2
  Find the density by weighing the object on the scale and taking the reading. Divide the volume of the object from the weight taken by the reading to obtain the density. The unit of the density depends on the units you used to conduct the calculation.
- 3
  Find the mass using the formula: Mass = Density x Volume (M = D x V). For example, if the density of an object is 35 grams/cubic inch and the volume is 20 inches, the mass would be 700 grams.
