Answer:
V₂ = 3.49 L
Explanation:
Given data:
Initial volume of oxygen = 12.8 L
Number of moles = 0.0498 mol
Final volume = ?
Final number of moles = 0.0136 mol
Solution:
According to Avogadro law the number of moles of gas and volume are directly related to each other at constant temperature and pressure.
V₁/n₁ = V₂/n₂
Now we will put the values in formula.
12.8 L /0.0498 mol = V₂/ 0.0136 mol
V₂ = 12.8 L× 0.0136 mol/0.0498 mol
V₂ = 0.174 L.mol/0.0498 mol
V₂ = 3.49 L
