Answer:
a) H2S:SO2 = 2:2 and O2:H2O = 3:2
Explanation:
⇒ H2S:SO2 = 2 mol H2S / 2 mol SO2 ≡ 2 : 2
⇒ O2:H2O = 3 mol O2 / 2 mol H2O ≡ 3 : 2
V = maximum capacity of human lung = 3 liter = 3 x 0.001 m³ = 0.003 m³ (Since 1 liter = 0.001 m³)
P = pressure of oxygen = 21.1 kilo pascal = 21.1 x 1000 = 21100 Pa (since 1 kilo = 1000)
T = temperature of air = 295 K
n = number of moles of oxygen
Using the ideal gas equation
PV = n RT
inserting the above values in the equation
(21100) (0.003) = n (8.314) (295)
n = 0.026 moles
Answer : The mass of 
is, 4.43 grams.
Explanation :
As we know that, when dissolve in water then it dissociates to give 2 mole of sodium ion 
and 1 mole of sulfate ion 
The chemical reaction will be:
Thus, the concentration of = 
First we have to calculate the moles of
Now we have to calculate the mass of
Molar mass of = 142 g/mol
Thus, the mass of is, 4.43 grams.
