The calculator is found on the right hand panel of the main page.The non metals obtain a stable outer or valence electron configuration by sharing electrons with one another.If youve ever been fooled by the old question, Which weighs more: a pound of feathers or a pound of lead then you wouldnt be alone.
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 theyre different concepts. Chemical Formula Name Converter How To Calculate DensityRead on to find out exactly what density is, how it works, and how to calculate density. Density is the mass per volume - not just the straight-up mass. Chemical Formula Name Converter Full Of FeathersSo 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. For an equal amount of space it takes up (volume), lead weighs much more than the feathers (mass). Density can also be thought of as how compacted or compressed a substance is. A pound of feathers is filled with airy space, so its not very dense at all, while a pound of lead feels much more solid, so its more dense. This is why you should never comment on your Auntie Mabels sponge cake by describing it as dense: she was probably going for something a little more airy. 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. Try mixing oil and water and see how they separate into layers, with the less dense oil on top. Always keep an eye on your units: its standard to use g or kg per cm or m, so use our unit converters if your measurements are in different units. Density is often written in mathematics as the symbol p or D. So, if you have a kilogram of cheese with the volume of 0.0002m, then not only are you in for some weird and wonderful dreams, but you also have cheese with a density of 5000kgm (p 1kg 0.0002m). The formula we showed you above (p mV) is the one we use to calculate density, but as there are three elements to that formula, it can be expressed in three different ways. ![]() For assistance with converting between units of mass and volume, give our weight and volume converter a try. Why not fill up your bath and try out some different materials to see what floats or sinks Just no electricals, please. Water has a density of 1000kgm, therefore anything that floats in water has less density than that, and anything that sinks has a greater density (for example, cooking oil is around 920kgm; tin is 7310kgm; cork is 240kgm; and Aerogel, one of the least dense solids we know of, has a density of 1kgm). So how come people float so easily in the Dead Sea Because its not just water. It has an incredibly high amount of salt in it, creating an overall density of 1240kgm.
