a)
0,7%+1%+2%+0.045%+0.03% = 3.775%
100%-3.775% = 96.225% Eisen
100%-(18%+10%) = 72% Stahl
72%*96.225% = 69.282%
b)
18% Chrom: 1500g*18% = 270g
10% Nickel: 1500g*10% = 150g
72% Stahl: 1500*72% = 1080g
Stahl
Eisen: 1080g*96.225%% = 1039.23g
Kohlenstoff: 1080g*0.7% = 7.56g
Silizium: 1080g*1% = 10.8g
Mangan: 1080g*2% = 21.6g
Phosphor: 1080g*0.045% = 0.486g
Schwefel: 1080g*0,03% = 0.324g
a) 96.225% vom Stahlanteil sind Eisen und damit 69.282% von der Gesamtmischung
b) Chrom = 270g
Nickel = 150g
Eisen = 1039.23g
Kohlenstoff = 7.56g
Silizium = 10.8g
Mangan = 21.6g
Phosphor = 0.486g
Schwefel = 0.324g
