The concentration of in the stack gas = 12 ppmv
That means 12 L of is present per
The given temperature is 273 K (0 C) and pressure is 1 atm. At these conditions, 1 mol of gas would occupy,
V = 22.4 L
1 mol occupies 22.4 L
Moles of =
Mass of = =μg
Converting :
=
Calculating the concentration in μg/:
Big very big hope dis helps im not sure but i think its rite
