A percentage is a pure, dimensionless number. It has neither length, nor area, volume, mass, temperature or any other dimension.
density
Percentage by Mass = Mass of substance of interest/Total Mass Percentage by Volume = Volume of substance of interest/Total Volume Converting from one to the other requires information about their relative densities.
The percentages refer to the amount of a substance of interest that is contained in a compound or mixture of that and other substances. Percentage by mass = 100*mass of substance of interest/total mass. Percentage by volume = 100*volume of substance of interest/volume mass. And, incidentally, the word is definition, not diffinition.
to find the volume you do base times width times height.
find the volume of the pool find the volume of one gallon in whatever unit you are using. divide pool volume by gallon volume
density
The percentage of nitrogen in pure, dry ,standard air is 78,084 % (by volume).
Percentage change in volume= Change in volume/intial volume X 100
The alcohol by volume percentage in this wine is 13.5.
Percentage by Mass = Mass of substance of interest/Total Mass Percentage by Volume = Volume of substance of interest/Total Volume Converting from one to the other requires information about their relative densities.
The alcohol by volume percentage in red wine typically ranges from 12 to 15.
They are different in non-homogeneous mixtures. Here's an example. If you put a few drops of water in a balloon, the contents are 99.9% (or so) water by weight and 99.9% (or so) air by volume.
To determine how many liters of oxygen is in a 40% concentration, you would need to know the total volume of the substance in question. Then, you would multiply the percentage (40%) by the total volume to find the volume of oxygen.
The volume percentage of argon in a gaseous mixture can be calculated using the ideal gas law equation, where the volume percentage of argon would be the volume of argon divided by the total volume of the mixture times 100.
The percentages refer to the amount of a substance of interest that is contained in a compound or mixture of that and other substances. Percentage by mass = 100*mass of substance of interest/total mass. Percentage by volume = 100*volume of substance of interest/volume mass. And, incidentally, the word is definition, not diffinition.
The medical term for the measurement of the percentage of red blood cells in the volume of blood is hematocrit.
it's the same as the molar percentage as 1 mol of gas will occupy 24.79dm3/mol at 25 °C no mater what the element/compound is so if you know the actual amounts calculate the molar fraction and that will give you the percentage
