Density Of Zinc G Ml
iv-4 Density
Density is the corporeality of affair in a given unit of volume. Information technology can be measured in grams per cubic centimeter (one thousand/cm3). It is a measure out of how tightly packed the atoms of a substance are. When we say that ice is less dense than water, nosotros mean that the water molecules are more tightly packed when they are in the liquid state. The formula for determining density is
or 
One always hears that musculus is denser that fat. This ways that I tin work out, not lose weight and nevertheless lose inches off my waist. This is because 1 pound of muscle will take up less infinite than 1 pound of fat.
Mass is typically measured in grams. Volume is typically measured in ml which is the same thing as cmthree (or cubic centimeters of cc. 1 ml = 1 cmiii = 1 cc)
The density of water is one.00 grand/ml. The density of some mutual elements are shown below:
Densities of selected elements
| element | density (g/cmthree) | appearance |
| aluminum | 2.70 | silvery white, metallic |
| antimony | 6.68 | silvery white, metal |
| cadmium | 8.64 | silvery white, metallic |
| carbon (graphite) | 2.25 | black, dull |
| chromium | 7.2 | steel gray, hard |
| cobalt | eight.ix | silvery grayness, metal |
| Copper Gilded | 8.92 19.3 | reddish, metallic xanthous, metallic |
| atomic number 26 | seven.86 | silver, metallic |
| pb | xi.iii | silvery-blueish white, soft, metallic |
| manganese | 7.two | gray pink, metallic |
| Nickel Platinum | 8.9 21.4 | silvery, metal silver, metal |
| silicon | two.32 | steel gray, crystalline |
| silverish | ten.v | argent, metallic |
| tin (gray) | 5.75 | grey |
| tin (white) | vii.28 | white metallic |
| Zinc | seven.fourteen | bluish white, metallic |
Sample problem: A solid has a mass of 128 g. It is a rectangular solid 1.0 cm by ii.0 cm by 3.0 cm. What is the density of the solid and what metal is it?
Volume = length x width x height = one cm x 2 cm x 3 cm = half dozen cm3 or 6 ml.
D= One thousand/V = 128 g / half dozen ml= 21.4 g/ml
The metal must be platinum!
