Answer:
V₂ = 5.07 L
Explanation:
Given data:
Initial volume of balloon = 7.60 L
Initial number of moles of oxygen = 2.67 mol
Final number of moles of oxygen = 1.78 mol
Final volume of balloon = ?
Solution:
According to the Avogadro law,
Number of moles of gas and volume are directly proportional to each other at constant temperature and constant pressure.
Mathematical relationship:
V₁/n₁ = V₂/n₂
No we will put the values.
7.60 L / 2.67 mol = V₂/1.78 mol
V₂ = 7.60 L× 1.78 mol/ 2.67 mol
V₂ = 13.528 L. mol /2.67 mol
V₂ = 5.07 L
