\(n_{Hg}=\dfrac{m}{M}=\dfrac{227}{2006}\left(mol\right)\)
\(PTHH:2Hg+O_2\rightarrow2HgO\)
\(.................\dfrac{227}{2006}.........\dfrac{227}{4012}............\dfrac{227}{2006}\)
\(\Rightarrow\left\{{}\begin{matrix}m_{HgO}=n.M=~24,5\left(g\right)\\V_{O_2}=n.22,4=~1,27\left(l\right)\end{matrix}\right.\)
Vậy ...
*Nung thủy ngân oxit:
nHgO = m/M = 22,7/217 ≃ 0,1 (mol)
PT:
2HgO --to--> 2Hg + O2
0,1 ----------> 0,1 --> 0,05 (mol)
Từ phương trình ta có:
VO2 = nO2 . 22,4 = 0,05 . 22,4 = 1,12 (l)
mHg = nHg . MHg = 0,1 . 201 = 20,1 (g)
