Avem : c1=20% ms1=200g +II(c2=30% ms2=300g)+III(40% ms3=400g)
a)Calculati Cf
b)Toate cele 3 solutii-450H2O ,cf2?
c)Cele trei solutii+ 450H2O cf3?
Ajutati-ma....
P.S care nu stie sa nu comenteze..Doar pt punte ca dau report
a) ms1c1+ms2c2+ms3c3=cf1*mf1 cf1=(200*20+300*30+400*40)/(200+300+400) ==> cf1=32,22% b) 200*20+300*30+400*40-450*0=cf2*(200+300+400-450) cf2=29000/450=64,44% c) 200*20+300*30+400*40+ 450*0 =cf3 (200+300+400+450) cf3=29000/1350=21,48%
