how would you find the density of an unknown liquid if you have all of the equipment of the laboratory equipment you need?
massvolume
A gram is a measure of mass, not of weight. The density of the liquid is 0.8 grams per mL.
Weigh it & measure its volume.
Density = mass/volumemass of unknown = 110.810 g - 82.450 g = 28.360 gvolume = 50.0 mlDensity = 28.36 g/50 ml = 0.567 g/ml (to 3 significant figures)
89.4 g/mol
you have to drink two cup of water and eat fish and you must know
A ruler.
Electronic balance
This depends on the nature and form of the sample:- for a solid with a regulate shape weight the sample and calculate the volume from the dimensions; density is the ratio between mass and volume. You can measure the volume of great sample by water displacement.- for other solids use a pycnometer- for liquids use a densimeter (simple or electronic)etc.

because can be dangerous
The density of einsteinium is 8,84 g/cm3.

massvolume
If your experiment shows that your unknown material has twice the density of your known material, you can simply look up the density of the control material and double it (or multiply by whatever the ratio is). This will give you the density of the unknown and you can attempt to identify it by looking for this number in a density table.
Unknown. Density is a function of volume, not area.
