What is percentage composition by volume?

Answer 1

% of Volume = (volume of solute) / (volume of solution) x 100

Ex: You have 40.0ml of C6H5CH3 that is put into 75.0ml of C6H6, what is the percent volume of C6H5CH3?

(40.0ml) / (115.0ml) x 100 = 34.8% of C6H5CH3

Answer 2

it not possible to measure the volume of air. but if you mean the percentage composition of gases in air, then it is 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases

Answer 3

volume percent = (volume of solute/volume of solution) x 100%

Answer 4

100 ppm = 0.1 parts per thousand and thus 0.01 parts per hundred = 0.01%

Answer 5

Let's say that 140 g vodka has 50 g ethanol.

100------------------x
x = (100 . 50)/140 = 35,7 %
