Question

1. Tính số mol của các chất sau

112 ml NO₂ ; 224 ml CO₂ ; 336 ml N₂O ; 672 ml Cl₂ ; 8,96 L O₂ ; 115 ml SO₂ ; 225 ml H₂S

Answer 1

\(n_{NO_2}=\dfrac{0,112}{22,4}=0,005\left(mol\right)\)

\(n_{CO_2}=\dfrac{0,224}{22,4}=0,01\left(mol\right)\)

\(n_{N_2O}=\dfrac{0,336}{22,4}=0,015\left(mol\right)\)

\(n_{Cl_2}=\dfrac{0,672}{22,4}=0,03\left(mol\right)\)

\(n_{O_2}=\dfrac{8,96}{22,4}=0,4\left(mol\right)\)

\(n_{SO_2}=\dfrac{0,115}{22,4}=\dfrac{23}{4480}\left(mol\right)\)

\(n_{H_2S}=\dfrac{0,225}{22,4}=\dfrac{9}{896}\left(mol\right)\)
