V=3m*4,5m*2,5m=33,75m³
Vn=78%*33,75m³=26,325m³
ς=m/V
m=ς*V
26,325m³=26325dm³
m=1,146g/dm³*26325dm³=30168,45g=30,16845kg ≈30,17kg
Vn=78%*33,75m³=26,325m³
ς=m/V
m=ς*V
26,325m³=26325dm³
m=1,146g/dm³*26325dm³=30168,45g=30,16845kg ≈30,17kg
m = 33750 x 1,146 = 38677,5 g = 38,7 kg
V= 3m x 4,5m x 2,5m = 33,75 m³
V azotu =78%*33,75m³=26,325m³
g= m/V
m= g x V
26,325m³ = 26325dm³
m= 1,146g/dm³ x 26325dm³ = 30168,45g = 30,16845kg =30,17kg
