Mass = Density x Volume Density = Mass ÷ Volume Volume = Mass ÷ Density
The idea is to use the formula mass = volume x density. Replace the numbers you know, and solve.
electrical conductivity of graphite?
Pencils were made of lead but it changed to graphite because they new the dangers of lead. 1564 was the time the United States switched to graphite
Graphite conducts electricity.
Yes, graphite is a good conductor of heat .
The volume of graphite is dependent on its mass and density. You can calculate it only if you know the sample's mass and density. The same goes for any other substance or object.
diamond
density = mass / volume
Graphite has a density of 2.09-2.23 grams/cubic centimeter. Therefore, a cubic foot of graphite weighs on average 134.2 pounds.
Graphite is less dense than diamond, due to the differences in crystal structure.
density = mass / volume Solving for mass: mass = density x volume Solving for volume: volume = mass / density
Get your life together and solve it.
D=m/v
Some allotropes of carbon are diamonds, amorphous carbon, and graphite. While the density of diamonds ranges between 3.15 and 3.53 grams per cubic centimeter, graphite has a density that is between 2.09 and 2.23 grams per cubic centimeter. The density of carbon is 2.267 grams per cubic centimeter.
Density = mass/volume Mass = Density x volume Volume = mass/density
For experimental calculation: Mass the graphite sample with a scale (make sure to take into account the mass of whatever is holding the graphite sample - either zero the scale with the beaker/holder before adding the sample or subtract the mass of the beaker/holder from the total mass). Measure volume by measuring water displacement when graphite sample is added to a measured amount of water. Density = (Mass) / (Volume)
I think there is not enough information to solve this question, but these formula's might be helpful: density = mass / volume volume = mass / density mass = volume * density
