Answer:
n₂ = 0.2 mol
Explanation:
Given data:
Volume of 1st balloon = 2.5 L
Moles of He in 1st balloon = 0.100 mol
Volume of second balloon = 5.0 L
Moles in second balloon = ?
Solution:
According to the Avogadro law,
Number of moles of gas is directly proportional to the volume of gas at constant temperature and pressure.
Mathematical expression:
V₁/n₁ = V₂/n₂
V₁ = Volume of 1st balloon
n₁ = Moles of He in 1st balloon
V₂ = Volume of second balloon
n₂ = Moles in second balloon
Now we will put the values.
2.5 L / 0.100 mol = 5 L /n₂
n₂ = 5 L× 0.100 mol /2.5 L
n₂ = 0.5 mol /2.5
n₂ = 0.2 mol
