Question

19. Vent pipes at solid-waste landfills often emit foul-smelling gases. A sample of such emissions has a density of
0.650 g/L at 25 °C and 757 mm-Hg. What is identity of the gas emitted with the choices of CH. C,Hs, Na, H,S?

Expert Solution

Step 1

Ideal gas equation is

PV = nRT

PV = $\frac{w}{M}$ RT [ moles(n) = $\frac{m a s s (w)}{m o l a r m a s s (M)}$ ]

PM = $\frac{w}{V}$ RT

PM = dRT [ density (d) = $\frac{w}{V}$ ]

M = $\frac{d R T}{P}$

P = pressure of gas

M = molar mass of gas

R = gas constant = 0.0821 L atm mol^-1 K^-1

T = Absolute temperature
