Question

Calculeaza volumul solutiei alcoolice 72% (ro=1,02 g/cm cubi) obtinui industrial din 67,2 m cubi etena la 80 atm si 350°C

Answer 1

poVo/TO=pV/T

1atmxVo/273=80x67,2/623

Vo=273x80x67,2/623

V0=2355,77m cubi

 

 

2355,77                     Y

CH2=CH2+ H2O→CH3-CH2-OH

22,4                          46

Y=2355,77X46/22,4

Y=4837,75 x1000KG ETANOL=4837750g

ρ=m/V

V=m/ρ

V=4837750/1,02

V=474264,70mL/1000=474,264l/10000=0,474m cubi
