Question

6,4g khí sunfuarơ SO₂ có thể tích là

A. 2,24 lít              B. 22,4 lít                C. 3,36 lít          D. 11,2 lít

Answer 1

\(n_{SO_2}=\dfrac{6,4}{64}=0,1\left(mol\right)\\ V_{SO_2\left(đktc\right)}=0,1.22,4=2,24\left(l\right)\)

Answer 2

\(n_{SO_2}=\dfrac{m}{M}=\dfrac{6,4}{64}=0,1\left(mol\right)\)

\(V_{SO_2}=n.22,4=0,1.22,4=2,24\left(l\right)\)

\(\Rightarrow A\)
