Ta có dx/kk
\(=\dfrac{M_X}{M_{kk}}\\ \Leftrightarrow2,207=\dfrac{M_X}{29}\\ \Rightarrow M_X=2,207.29=64dvC\)
Viết CTHH SxOy
\(Ta.có:m_S=\dfrac{\%S.M_X}{100\%}=\dfrac{50\%.64}{100}=32\left(g\right)\\ n_S=\dfrac{m_S}{M_S}=\dfrac{32}{32}=1\left(mol\right)\\ \Rightarrow x=1\\ m_O=m_X-m_S=64-32=32\left(g\right)\\ n_O=\dfrac{m_O}{M_O}=\dfrac{32}{16}=2\left(mol\right)\)
=>y=2
Vậy CTHH là SO2
\(a.d_{\dfrac{X}{kk}}=2,207\\ M_{kk}=29\\ M_X=d_{\dfrac{X}{kk}}.M_{kk}=2,207.29=64\left(\dfrac{g}{mol}\right)\)
\(b.m_S=64.50\%=32\left(g\right)\\ m_O=64-32=32\left(g\right)\\ n_S=\dfrac{32}{32}=1\left(mol\right)\\ n_O=\dfrac{32}{16}=2\left(mol\right)\\ CTHH:SO_2\)
