Most of the sulfur used in the United States is chemically synthesized from hydrogen sulfide gas recovered from natural gas well

galben [10]

Answer:

$0.21\ \text{kg/s}$

Explanation:

P = Pressure = $0.48\ \text{atm}=0.48\times 101325\ \text{Pa}$

V = Volume = $450\ \text{L/s}=450\times 10^{-3}\ \text{m}^3/\text{s}$

R = Gas constant = $8.314\ \text{J/mol K}$

T = Temperature = $(264+273.15)\ \text{K}$

The reaction is

$2H_2S+3O_2\rightarrow 2SO_2+2H_2O$

From ideal gas equation we have

$PV=nRT\\\Rightarrow n=\dfrac{PV}{RT}\\\Rightarrow n=\dfrac{0.48\times101325\times 450\times 10^{-3}}{8.314\times (264+273.15)}\\\Rightarrow n=4.9\ \text{mol}$
