Answer:
16 moles
Explanation:
from the equation:
4Fe + 3O2 -----> Fe2O3
the mole ratio of Fe to O2 follows,
3 moles O2 reacts with 4 moles Fe.
therefore,
1 mole O2 reacts with 4/3 moles Fe
and 12 moles O2 reacts with (4/3) × 12 moles Fe = 16 moles
Answer:
V₂ = 1.51L
Explanation:
According to Boyle's law:
P₁V₁ = P₂V₂
From the given parameter
P₁ = 153kPa
V₁ = 3.00L
P₂ =304kPa
V₂ = ?
Making V₂ the subject of the formula, we have:
V₂ = P₁ V₁/P₂
V₂ = 153 ₓ 3/304
V₂ = 1.51L
