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.
density
A percentage is a pure, dimensionless number. It has neither length, nor area, volume, mass, temperature or any other dimension.
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.
Question is not clear...what do you mean?
your crime rate is the percentage of the crime, and the volume is the number of crimes
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.
The alcohol by volume percentage in this wine is 13.5.
Percentage change in volume= Change in volume/intial volume X 100
ABV (Alcohol by Volume) measures the percentage of alcohol in a beverage based on the total volume, while ABW (Alcohol by Weight) measures the percentage of alcohol based on the total weight. ABV is more commonly used and provides a higher percentage compared to ABW for the same beverage.
To calculate the inaccuracy of a pipette, you would compare the actual volume dispensed by the pipette with the desired volume. This can be done by using a calibrated scale and measuring the difference between the intended volume and the dispensed volume. The inaccuracy can be expressed as a percentage of the intended volume.
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.
The medical term for the measurement of the percentage of red blood cells in the volume of blood is hematocrit.
