Mass divided by volume, same as it is for anything else.
The density of metals ranges from around 500 kg/cubic meter up to around 22000 kg/cubic meter, so if you were hoping for a value ... somewhere in that range, which is a pretty wide range, depending on which specific metal you're talking about.
Metals have a wide range of densities, but there are A LOT of metals, so you do get metals with similar densities. So yes, if you get a really accurate measure of a metal's density and you are fairly certain it is a pure metal (not an alloy), then you should be able to identify it by its density.
The mass m/g of the metal is found.
The volume of the metal is then found by the displacement method.
This is done by placing a volume of water V1/cm3 in the measuring cylinder.
The metal is then placed in the measuring cylinder and the new volume V2/cm3 is read off. The volume V/cm3 of the metal is (V2 - V1) cm3
The density d of the metal is calculated by : (m/V) gcm-3
The value of d is then compared to the densities of the metals in the table. If the metal is pure, the value of d will coincide with one value in the table.
You would use the balance to measure the mass of the sample of metal. You would then use the displacement method to measure the volume of the sample of metal. The displacement method is when you put some water in the graduated cylinder then drop the sample of metal in. However much the volume of water has increased in the graduated cylinder is the volume of that sample of metal. Next you calculate the density of the sample of metal by dividing the mass by the volume. Finally, you look up the density you calculated on the table of densities to identify the sample of metal.
You can compare the density with a table of known densities. Now, in many cases, you'll have several substances with very similar densities, so you'll probably need additional information.
yea if its a pure element of one kind
Balance measures weight. The graduated cyliner measures volume. Think scale and measuring cup.
triple beam balance
the laboratory instruments are meter stick , incubator
Prior to weighing anything on a balance, you would want to lay a piece of weighing paper on the pan and tare the balance (zero it out). Following this, you could use a clean metal scoop to transfer solid to the weigh paper for weighing.
The term specific gravity means density in comparison to that of water. Density is weight divided by volume. So to get the volume, pour the oil into a graduated cylinder or measuring cup (same principle). To get the weight, use a scale (a chemist would use a triple beam balance). Once you have the density you can divide it by the density of water, and the result is the specific gravity.
Both a balance and a graduated cylinder are used as measuring instruments, with the balance applied to discover weight and the graduated cylinder used to discover volume.
The balance and the graduated cylinder are both used to make measurements.
The cylinder measures volume, the balance measures weight.
They are two different ways of measuring. A balance measures weight (or technically, mass) while a graduated cylinder measures liquid volume.
A balance.
The cylinder measures volume, the balance measures weight.
well with a graduated cylinder you can measure liquid
A graduated cylinder is a glass or plastic device used in laboratory to measure volume of liquids.
Balance measures weight. The graduated cyliner measures volume. Think scale and measuring cup.
