Answer: 34.4 g
Explanation:
As 
is in excess, 
is the limiting reagent and thus it will limit the formation of products.
According to stoichiometry:
2 moles of hydrogen produce = 1 mole of 
2.5 moles of hydrogen produce = 
of
Mass of 
But as % yield is 86%, mass of produded is 
Thus 34.4 g of is produced.
Answer:
V₂ = 155.2 mL
Explanation:
Given data:
Initial volume =175.6 mL
Initial pressure =0.9648 atm
Initial temperature = 298.1 K
Final temperature = 273 K
Final volume =?
Final pressure = 1 atm
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
P₁V₁/T₁ = P₂V₂/T₂
V₂ = P₁V₁T₂ /T₁P₂
V₂ = 0.9648 atm × 175.6 mL × 273 k / 298.1 K× 1 atm
V₂ = 46251.4 atm. k. mL/ 298.1 K× 1 atm
V₂ = 155.2 mL
