Density is defined as mass per unit volume, so it is necessary to measure both the weight and volume of an object to determine its density. Use a scale to measure the object's weight. A ruler can be used to measure the dimensions of an object and calculate its volume.
Continue ReadingThe volume of irregularly shaped solids can be found by using the displacement method, which the object is placed in a graduated cylinder containing a known volume of water. The subsequent change in water level is equal to the volume the object displaces. When calculating the density of a liquid, a graduated cylinder can be used to measure the liquid's volume.
Learn more about MeasurementsAs grams are a unit of mass and milliliters are a unit of volume, you need to know the density of the substance you are measuring in milliliters in order to convert the measurement from milliliters to grams. In the case of water, 1 gram = 1 milliliter, so 15 milliliters of water = 15 grams.
Full Answer >Air density is the mass of air per unit of volume it occupies, and it is expressed in kilograms per cubic meter when using the metric system. In the free atmosphere, air density decreases when temperature increases or when the air is humid. However, air density increases when pressure increases.
Full Answer >According to the science department at Elmhurst College, the density of an object is how relatively heavy an object is at a fixed volume. Mathematically, the definition of density is mass divided by volume, where the standard mass is in grams and the standard volume is in milliliters.
Full Answer >The formula for density, which is mass divided by volume, can be manipulated to have the volume as the unknown. Given the mass and the density, the volume can be found by dividing the mass by the density.
