The SI unit for density is kilograms per cubic meter (kg/m³). That is very small for solids and liquids but greater for gases. Free online Density calculator with which you can calculate the density of any substance given its mass and volume. Try mixing oil and water and see how they separate into layers, with the less dense oil on top. The density of a material can be changed by temperature and pressure. If one side of the cube measures 4 cm, what is the density of the aluminum A teacher performing a demonstration finds that a piece of cork displaces 23.5 mL of water. A machine shop worker records the mass of an aluminum cube as 176 g. Density Calculator computes the density (d m/v), mass (m dv) and volume (v m/d). When you mix two or more substances, the most dense substance sinks to the bottom, whilst the least dense substance is more buoyant and floats to the top. Calculate the volume of a liquid with a density of 5.45 g/mL and a mass of 65 g. This is why you should never comment on your Auntie Mabel's sponge cake by describing it as dense: she was probably going for something a little more airy.ĭensity is also what makes things float or sink. A pound of feathers is filled with airy space, so it's not very dense at all, while a pound of lead feels much more solid, so it's more dense. For an equal amount of space it takes up (volume), lead weighs much more than the feathers (mass).ĭensity can also be thought of as how compacted or compressed a substance is. So if the question was, 'Which weighs more: a 500ml jug full of feathers or a 500ml jug full of lead?' then the answer would be the lead. What is density?ĭensity is the mass per volume - not just the straight-up mass. Read on to find out exactly what density is, how it works, and how to calculate density. Hydrogen - System Mass Calculator Calculate the hydrogen density and the overall system mass based on the volume, temperature and pressure: H 2 Density 14.506 kg/m 3 Overall system mass 1. This free density calculator determines any of the three variables in the density equation given the other two. The SI unit of density is kilogram per cubic meter (kg/m3). This calculator can help you obtain accurate and reliable results. Density is defined as its mass per unit volume. Density is a measure of how much mass is contained in a given unit volume (density mass/volume). Although the feathers and the lead both weigh exactly the same (um, a pound), their density is wildly different, and we can sometimes mentally conflate weight and density - even though they're different concepts. Density Calculator computes the density (d m/v), mass (m dv) and volume (v m/d). The density calculator finds density using the given mass and volume. Density is defined as mass per unit volume. Step 1: Enter the values of mass and volume below using which you want to calculate the density. The calculator can use any two of the values to calculate the third. If you've ever been fooled by the old question, ' Which weighs more: a pound of feathers or a pound of lead?' then you wouldn't be alone. Density Equation for these Calculations: p m V Where: p density m mass V volume The Density Calculator uses the formula pm/V, or density (p) is equal to mass (m) divided by volume (V). For example, if you are starting with mm and you know a and h in mm, your calculations will result with V in mm 3.īelow are the standard formulas for volume.To calculate density: p = m/V To calculate mass: m = pV To calculate volume: V = m/p The units are in place to give an indication of the order of the results such as ft, ft 2 or ft 3. Molarity Calculator First you must calculate the number of moles in this solution, by rearranging the equation. Units: Note that units are shown for convenience but do not affect the calculations. Online calculator to calculate the volume of geometric solids including a capsule, cone, frustum, cube, cylinder, hemisphere, pyramid, rectangular prism, sphere and spherical cap.
