a) tlenek azotu (III) - N2O3
mN= 12u , mO= 16u
mN2 = 12u * 2 = 24u
mO3 = 16u * 3 = 48u
mN2O3 = 24u + 48u = 72 u
100% = 72 u
X = 24u
X = 100*24/ 72
X= 33%
Cp N = 33%
Cp O = 100% - 33% = 67%
b) siarczek potasu - K2S
mK= 39u
mS= 32u
mK2 = 39u * 2= 78u
mK2S = 110u
100% = 110u
X = 78 u
X = 100*78 /110
X= 71 %
Cp K = 71%
Cp S = 100% - 71% = 29%
Wyjaśnienie:
Wszystko ok. Pozdrawiam.
