Đặt
VA=a
VB=b
VC=a+b
\(\rightarrow\text{mA=14300a mB=1090b}\)
\(\rightarrow\text{mC=14300a+1090b}\)
\(\rightarrow VC=\frac{\text{14300a+1090b}}{\text{1,22}}\)
\(\rightarrow\text{nH2SO4 C}=\frac{\text{14,3a+1,09b}}{\text{1,22.6,1}}\)
\(\rightarrow\text{nH2SO4 A=14,3a}\)
nH2SO4 B=2,18b
->nH2SO4 c=14,3a+2,18b
Ta có :
\(\frac{\text{14,3a+1,09b}}{\text{1,22.6,1}}=\text{14,3a+2,18b}\)
Chọn a=1 \(\rightarrow b=\frac{88}{47}\)
\(\rightarrow\frac{MA}{MB}=7\)
