Explanation / Answer

2 H2S + 3 O2 ----------------------> 2 SO2 + 2 H2O

2 mol                                              2 mol

1.26 mol                                     1.26

moles of SO2 = 1.26

pressure = 1 atm

temperature = 0 + 273 = 273

P V = n R T

1 x V = 1.26 x 0.0821 x 273

V = 28.2 L

volume of SO2 = 28.2 L
