Answer to Question #108157 in General Chemistry for Azaria

Question

What is the volume of Oxygen required to produce 300cm3 of SO3 at room temperature and pressure

Answer 1

2S+3O₂=2SO₃

300 ml = 0,3l

n(SO₃)=V(SO₃)/V_m=0,3/22,4=0.013mol

n(O2)=0.013*3/2=0.0195mol

V(O2)=0.0195×22,4=0.437l=437ml

Answer 437ml
