\(n_{SO_3}=\dfrac{16}{80}=0,2\left(mol\right)\) | \(0,2.6.10^{23}=1,2.10^{23}\left(p.tử\right)\) |
\(n_{NaOH}=\dfrac{8}{40}=0,2\left(mol\right)\) | \(0,2.6.10^{23}=1,2.10^{23}\left(p.tử\right)\) |
\(n_{Fe_2\left(SO_4\right)_3}=\dfrac{16}{400}=0,04\left(mol\right)\) | \(0,04.6.10^{23}=2,4.10^{22}\left(p.tử\right)\) |
\(n_{Al_2\left(SO_4\right)_3}=\dfrac{34,2}{342}=0,1\left(mol\right)\) | \(0,1.6.10^{23}=6.10^{22}\left(p.tử\right)\) |
a) \(n_{SO3}=\dfrac{16}{80}=0,2\left(mol\right)\)
⇒ \(A=0,2.6.10^{-23}=1,2.10^{-23}\) (phân tử)
b) \(n_{NaOH}=\dfrac{8}{40}=0,2\left(mol\right)\)
⇒ \(A=0,2.6.10^{-23}=1,2.10^{-23}\) (phân tử)
c) \(n_{Fe2\left(SO4\right)3}=\dfrac{16}{400}=0,04\left(mol\right)\)
⇒ \(A=0,04.6.10^{-23}=0,24.10^{-23}\) (phân tử)
d) \(n_{Al2\left(SO4\right)3}=\dfrac{34,2}{342}=0,1\left(mol\right)\)
⇒ \(A=0,1.6.10^{-23}=0,6.10^{-23}\) (phân tử)
