Question

cum fac problema 75?

Answer 1

Calculam masa de acetaldehida din solutie:
40/100=md/6750kg => md=2700kg obtinute cu randament de 90%
90/100=2700kg/masateoretica => masateo=2700*100/90=3000kg acetaldehida
22,4m³.............30kg
CH4 + ½O2 -> CH2=O + H2
x=2240m³.......3000kg
89,6/100=2240/Vimpur => Vimpur=2240*100/89,6=2500m³ CH4
=> a)
