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.
porosity of the rock.
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 percentage composition of a mixture has nothing to do with its homogeneity or otherwise. A mixture is homogeneous if its percentage composition - whatever that is - is the same throughout the mixture.
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
To convert 2 liters to a percentage, you need to know the total volume it is a percentage of. If we assume the total volume is 100 liters, then 2 liters would be 2% of the total volume. Therefore, 2 liters is equal to 2% when considering a total volume of 100 liters.
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.
yes. only the percentage is known (78.09%), because it is impossible to measure the total volume of air ( constantly changing).
Porosity= Volume of void space/ Total volume of the solidThis is a good way for soil, If you have the initial volume of the soil then all you have to do to find the void space is saturate it with water. As long as you know the weight different between before and after saturation you can find the void space because we know that water's density is about 1g/cm^3.So,Porosity= ((mass of saturated soil - mass of original soil) Density of water) / Volume of original soilThis also works.
The volume of nitrogen in Earth's atmosphere is approximately 78% of the total volume at sea level, which is roughly 78.08%. The volume of nitrogen is expressed as a percentage of the total volume of gases in the atmosphere.
Porosity is the percentage of void space in a rock. It is defined as the ratio of the volume of the voids or pore space divided by the total volume. It is written as either a decimal fraction between 0 and 1 or as a percentage. For most rocks, porosity varies from less than 1% to 40%.
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.
