Gọi số MOL dd H2SO4 =1 mol
=> m\(_{H2SO4}=98\left(g\right)\)
m\(_{dd}=\frac{98.100}{10}=980\left(g\right)\)
m\(_{Muối}=M+96\left(g\right)\)
MCO3+ H2SO4---->MSO4+H2O+CO2
1------------1-------------1---------------1
m\(_{MCO3}=M+60\left(g\right)\)
m\(_{CO2}=4,4\left(g\right)\)
mdd=980+M+60-4,4=1035,6+M(g)
Theo bài ra ta có
\(\frac{M+96}{1035,6+M}.100\%=28,169\%\)
=> \(\frac{M+98}{M+1035,6}=0,28169\)
Tự lm tiếp nhé
