In one cubic meter of air 0.21 m3 of oxygen. Find the percentage ratio of oxygen in a room with measurements of 7m 4m 3m to oxygen in 1m3
Find the volume of the room (multiply its dimensions):
7 * 3 * 4 = 84 m ^ 2.
Then the amount of oxygen in the room is equal to:
84 * 0.21 = 17.64 m ^ 2.
Find the volume ratio and multiply it by 100:
0.21 / 17.64 * 100 = 1.19%.
Answer: 1 m ^ 3 contains 1.19% of the oxygen contained in the room).
