Percent of an objects mass is expressed in terms of its weight. Percent of an objects volume is expressed in terms of its size.
A kiloliter is a volume measure, and kilogram is a mass measure.
Volume = mass / Density Mass = Volume * Density Density = Mass / Volume
density = mass / volume Solving for mass: mass = density x volume Solving for volume: volume = mass / density
Density = mass/volume Mass = (density) x (volume) Volume = mass/density
Density = Mass / Volume Mass = Density * Volume Volume = Mass / Density
% of volume = 100*(volume of substance that you are interested in)/(total volume) % of mass = 100*(mass of substance that you are interested in)/(total mass).
Percent per mass is exprimed in g/Kg, mg/kg, µg/kg, etc. Ex.: An ore contain 10 mg gold/kg ore. Percent per volume is exprimed in volume to volume. Ex.: Vodka contain 40 volumes of ethanol/100 volumes of liquid.
Density
Mass it how many particles an object has and volume is the space it takes up.
mass deals with density and volume but size deals with volume only.
Percent per mass example: uranium concentration in granite is approh. 4 mg/kg. Percent per volume: uranium concentration in ocean water is approx. 4 micrograms/L.
Mass is the amount of matter in an object. Volume the amount of space an object has.
(mass /volume)x100
mass is weight. volume accounts for size. density of items change therefore masses are not the same as volumes
Mole percent vs volume percent is a simple comparison to make. Mole percent is equivalent to moles of substance/moles of total x 100. Volume percent is volume of substance/volume of total x 100.
Percent composition is usually expressed as a percent by mass, but in the case of gases and vapors, it is often expressed as a percent by volume.
It makes no difference. Density = mass / volume. You divide the mass by the volume. If the volume is greater than the mass your answer will necessarilybe less than one, but that is still the correct answer showing the density in terms of the units used.
