Percent Composition of Compounds Percent by Mass Chemical formulas show the ratio of atoms in a compound. Sometimes, it is helpful to..
That's why expressing composition as volume percentages works. Wow, this is very easy to understand. If I say, I have 5 dm^3 of air in the container with the pressure of 3 atm. Let's say oxygen is 20 percent by volume in the air. First, I have to have (20/100)*5 = 1 dm^...
