Density. The density of graphite is 2.266 g/cm3 and the density of diamond is 3.51g/cm3. It is easy to calculate density if you know the formula and understand its related units. Sign in, choose your GCSE subjects and see content that's tailored for you. Though SI unit of density is kg/m³, for convenience we use g/cm³ for solids, g/ml for liquids, and g/L for gases. Mathematically, the density of an object is expressed as follows: Each substance has a specific density. Read about our approach to external linking. Since the number of balls in the second box is 6 times the first box, the second box would weigh more. Density is essentially a measurement of how tightly matter is packed together. It is also frequently represented in the cgs unit of grams per cubic centimeter (g/cm 3). \[\text{Density} = \frac{\text{mass}}{\text{volume}}\]. Our team of exam survivors will get you started and keep you going. Materials that are dense are most likely to ‘feel’ heavy or hard. Your email address will not be published.

Bulk density, also called apparent density or volumetric density, is a property of powders, granules, and other "divided" solids, especially used in reference to mineral components, chemical substances, ingredients, foodstuff, or any other masses of corpuscular or particulate matter. The principle of density was discovered by the Greek scientist Archimedes. It is a unique physical property for a particular object. The principle of density was discovered by the Greek scientist Archimedes. The density of a substance is the measure of how much stuff an object has in a unit volume. Calculate the density of water if it has a mass of 1160 Kg and a volume of 1 m, If you find a shiny rock, a carbon allotrope with a volume of 0.042 cm³ and a mass of 0.14 g, is it graphite or diamond? Many applications of density are there in our real-life like a few examples are in pipe design, shipbuilding, helium balloons, weight distribution in the airplane, and the fact that ice floats on water. The density of graphite is 2.266 g/cm, = 2.266 g/cm³ x 0.042 cm³ = 0.0951g for graphite. Talking about other density units, metric tons and liter are also used even though they are not part of the SI. m = 2.266 g/cm³ x 0.042 cm³ = 0.0951g for graphite, m = 3.51g/cm3 x 0.042 cm³ = 0.1474 g for diamond. The formula for density is d = M / V, where d is density, M is mass, and V is volume. Fill the first box with x balls and the second box with 6x balls. We use rounding at unit-conversion.info. If the mass of each ball is the same, which box would weigh more? Use the density equation to solve for m, mass of graphite and for the mass of a diamond.
