Chapter 1: Problem 21

State Avogadro's law.

Short Answer

Expert verified
Answer: Avogadro's Law states that, at the same temperature and pressure, equal volumes of all ideal gases contain the same number of particles, or moles. To explain this, let's take an example of two different gases (gas A and gas B) that are kept at the same temperature and pressure conditions. If both gas A and gas B occupy a volume of 10 liters, then according to Avogadro's law, they both contain the same number of moles. So if gas A has 2 moles, gas B should also have 2 moles.

Step by step solution

01

State Avogadro's Law

Avogadro's law states that, at the same temperature and pressure, equal volumes of all ideal gases contain the same number of particles, or moles. It is named after the Italian scientist Amedeo Avogadro. The relationship can be represented mathematically as: V ∝ n Where, V = volume of the gas, n = number of moles of the gas, and ∝ indicates proportionality.
02

Explain Avogadro's Law with an example

To better understand Avogadro's law, imagine two different gases (gas A and gas B) that are kept at the same temperature and pressure conditions. Let's say both gas A and gas B occupy a volume of 10 liters. According to Avogadro's law, since both gases occupy the same volume and are under the same temperature and pressure conditions, they both contain the same number of moles. So if gas A has 2 moles, gas B should also have 2 moles.
