A 7.60 L balloon contains 2.67 moles of oxygen gas. Some oxygen is released, so the only 1.78 moles of oxygen remain in the balloon. What is the new volume of the balloon?

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
