82 X 10-6 glm3of pollutants in the air. ... The weight of 1m3 of air is approximately 1.3 X 103g.Suppose that the volume of air inside of a building is 3 x 106 m3.
Answer:
If I'm correct, the answer is 1296.
Step-by-step explanation:
6 x 6 x 6 x 6 = 1296
First do 70+24=94
Then do 180-94=86
Next 86+54=140
Then 180-140=40
Next 40+80=120
Lastly 180-120=60
X=60
1. 45*x/100=90
x=100*90/45
x=200
2. 24=x/100*52
x=24*100/52≈46,15
4.125=30/100*x
x=125*100/30
x≈416,67
