if you mean air then its nitrogen.. but i dont know anything else
This is (mass of solute) divided by (mass of total solution) expressed as a percentage. The solute is what you are dissolving into the solution. Example: you have 90 grams of water, and you add 10 grams of salt (sodium chloride). The water is the solvent, sodium chloride is the solute, and the solution is salt water. 90 grams + 10 grams = 100 grams (mass of total solution). (10 grams) / (100 grams) = 0.1 --> 10% mass mass percent concentration.
Mass percent = grams of solute/total grams of solution Mole fraction = mols component/total mols mix. Molarity = mols solute/L solution Molality = mols solute/kg solvent Hope this helps :)
Percent by mass = (100) times (mass of the ingredient of interest) divided by (mass of the whole mixture)
Percent of an objects mass is expressed in terms of its weight. Percent of an objects volume is expressed in terms of its size.

Troposphere
The troposphere contains 75 percent of atmosphere's mass- on an average day the weight of the molecules in the air is14.7 lb..(sq. in.)- and most of the atmosphere's water vapor.

There are a few layers to the atmosphere however the Troposphere is the largest part of the atmosphere containing 75% of its mass. However the Troposphere contains 99% of the water vapour on the planet as well as Earth's aerosols. It is also where all weather phenomenon will occur.
Almost 90 percent of the atmosphere's total mass is contained below 16 km. 99.999percent is below 100 km which is the Karman Line the demarcation which marks the beginning of space.
It contains 70-80% of the total mass of the earth's atmosphere and 99% of water vapour.
