There are 100 liters of air: 1) How many liters of nitrogen are there in 100 liters of air. 2) What is the volume of oxygen in 100 liters

There are 100 liters of air: 1) How many liters of nitrogen are there in 100 liters of air. 2) What is the volume of oxygen in 100 liters of air. 3) What is the volume of carbon dioxide in 100 liters of air

Air is a mixture of different gases. The largest mass fraction is nitrogen – 78%; oxygen – 21%, carbon dioxide – 0.03%. Having mass fractions of gases, you can calculate their mass. 100 liters of air is 100%, and there is 78% nitrogen, add the proportion: 100 * 78/100 = 78 liters of nitrogen in one hundred liters of air. We also count for oxygen: 100 * 21/100 = 21 liters of oxygen in one hundred liters of air. And for carbon dioxide: 100 * 0.03 / 100 = 0.03 liter of carbon dioxide in one hundred liters of air.
