Question

làm giúp mình với câu 5 mình làm đc

Answer 1

1.

\(V=22,4.\left(0,2+0,15\right)=7,84\left(l\right)\)

Answer 2

2.

\(n_{CO_2}=\dfrac{6,72}{22,4}=0,3\left(mol\right)\)

Answer 3

3.

a, \(n_{CO_2}=\dfrac{4,4}{44}=0,1\left(mol\right)\)

\(\Rightarrow V_{CO_2}=22,4.0,1=2,24\left(l\right)\)

b, \(n_{O_2}=\dfrac{6,4}{32}=0,2\left(mol\right)\)

\(\Rightarrow V_{O_2}=22,4.0,2=4,48\left(l\right)\)

Answer 4

4.

\(n_{SO_2}=\dfrac{2,24}{22,4}=0,1\left(mol\right)\)

\(\Rightarrow m_{SO_2}=64.0,1=6,4\left(g\right)\)
