A blood test performed on whole blood to determine the percentage of red blood cells in the total blood volume is called a hematocrit test. It measures the proportion of red blood cells to the total blood volume, providing insights into a person's overall blood health and can help diagnose conditions such as anemia or polycythemia. The results are typically expressed as a percentage.
To determine the percentage of empty space in a square cleaning sponge, you would first calculate the total volume of the sponge. Then, measure the volume of the material in the sponge (not including empty space). Finally, divide the volume of empty space by the total volume and multiply by 100 to get the percentage of empty space.
Hematocrit measures the volumeof packed RBCs as a percentage of blood volume.
It is called its porosity.
Hematocrit ^_______^
Percentage change in volume= Change in volume/intial volume X 100
Finding the volume of an irregular object is called displacement method or water displacement method, where the object is submerged in water in a container and the volume of water displaced is measured to determine the volume of the object.
The alcohol by volume percentage in this wine is 13.5.
You would determine the volume of water it displaces and measure it.
porosity of the rock.

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.
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.
