Question

Two moles of gas A spontaneously convert to 3 moles of gas b in a container where the temperature and pressure are held constant. The sample originally took up 13.9L of volume. What is the new volume of the products? Pls show work :)

Answer 1

At constant temperature and pressure, If the amount of gas increases to the given value, its volume also increases to 20.85L.

What is Avogadro's law?

Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules."

It is expressed as;

V₁/n₁ = V₂/n₂

Given the data in the question;

• Initial amount of gas n₁ = 2moles

• Initial volume v₁ = 13.9L

• Final amount of gas n₁ = 3moles

• Final volume v₂ = ?

V₁/n₁ = V₂/n₂

V₁n₂ = V₂n₁

V₂ = V₁n₂ / n₁

V₂ = (13.9L × 3moles) / 2moles

V₂ = 41.7molL / 2mol

V₂ = 20.85L

Therefore, at constant temperature and pressure, If the amount of gas increases to the given value, its volume also increases to 20.85L.
