a/ Ta có: \(n_S=\dfrac{0.32}{32}=0.01\left(mol\right)\)
PTHH:
\(S+O_2\underrightarrow{t^o}SO_2\)
1 1
0.01 x
\(=>x=\dfrac{0.01\cdot1}{1}=0.01=n_{O_2}\)
\(=>V_{O_2}=0.01\cdot22.4=0.224\left(l\right)\)
b/ PTHH:
\(S+O_2\underrightarrow{t^o}SO_2\)
1 1
0.01 y
\(=>y=\dfrac{0.01\cdot1}{1}=0.01=n_{SO_2}\)
\(=>m_{SO_2}=0.01\cdot\left(32+16\cdot2\right)=0.64\left(g\right)\)
