Question

state and explain Avogadros law​

Answer 1

Answer:

Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.

Avogadro's law investigates the relationship between the amount of gas (n) and volume (v). It's a direct relationship, meaning the volume of a gas is directly propotional to the number of moles the gas sample present. The law is important because helps us save time and money in the long-run.

Answer 2

Hi friend_______,

Avogadro's Law:

★ Equal volumes of all gases under similar conditions of temperature and pressure contain equal number of molecules.

$\boxed{ \tt \: V \: \alpha \: n}$

$\sf \: \frac{V_{1}}{n_{1}}=\frac{V_{2}}{n_{2}}=constant$

where V1 & n1 are the volume and number of moles of a gas and V2 & n2 are a different set of values of volume and number of moles of the same gas at same temperature and pressure.

Applications of Avogadro's Law:

♦ It explains Gay-Lussac's Law.

♦ It helps in the determination of atomicity of gases.

♦ Molecular formula of gases can be derived using Avogadro's law.

♦ It determine the relation between molecular mass and vapour density.
