1. Avogadro’s law states that the volumeof any gas is proportional to the amount of gas in moles when the temperature and pressure remain constant. In other words, equal volumes of any gas contain the same number of molecules if the conditions do not change. Note that masses of the different gases will not be the same because they have different molecular masses. A balloon filled with helium will be 33 times lighter than a balloon filled with xenon gas. A moleis a measure of the quantity of a substance. A mole of a substance is defined as exactly 6.022 140 76 × 10²³ particles (atoms, molecules, ions, or electrons). A mole of a substance measured in grams is numerically equal to the average mass of one molecule of the compound, in unified atomic mass units. For example, one mole of oxygen with an atomic mass of 16 corresponds to 16 grams of this gas. One mole of an ideal gas at standard conditions occupies 22.4 liters. The number 6.022 140 76 × 10²³ is called the Avogadro constant. A mo...

1. An electron microscope is a particular type of microscope that illuminates the sample with a beam of accelerated electrons. This electron will be needed to have a very short wavelength, approximately 100,000 times shorter than the visible light, hence, giving the electron microscope a better resolution characteristic than an optical microscope. This can be heavily used to observe tiny things such as atoms and molecules. A transmission electron microscope can extensively achieve better than 50 Picometer (10-12) resolution, and we should also remember that atoms range from 30 – 300 Pico meters. There is another interesting fact that the radius of an atom is approximately more than 10000 times the radius of the nucleus and the atom is 99.999999% space. Before any of the technological advancements in the peripheries, we had only come to know about the rough estimate of the size of the atom even after the Rutherford alpha particle which on scattering experiment gave us the size of the nu...

Frequently Asked Questions

How is the number of atoms in Avogadro's number equal to?

Avogadro's number is equal to the number of molecules in one gram mole or one gram molecular mass of any compound. Thus gram molecular mass of any substance is equal to the mass in grams of Avogadro's number of 6.022 × 10 23 molecules. Avogadro's number is equal to the number of atoms in one gram mole or one gram atomic mass of an element

How to calculate Avogadro's law for a gas?

Avogadro's law calculator The Avogadro law states that at constant pressure and temperature, two volumes of two ideal gases have the same molar volume. In other words, at constant pressure and temperature, two equal volumes of ideal gases contain the same number of molecules. The Avogadro law is one of the components of the ideal gas law.

How is the Avogadro constant used to calculate mass?

The Avogadro constant can be used to calculate the mass of an atom in grams: Calculate the mass of a magnesium atom. (Relative atomic mass, Ar = 24.3) It is important to give the final answer to the lowest number of significant figures used in the calculation. In this example, this is the same number of significant figures as the Ar value.

Which is the best description of Avogadro's law?

Avogadro's law. Avogadro’s law, a statement that under the same conditions of temperature and pressure, equal volumes of different gases contain an equal number of molecules. This empirical relation can be derived from the kinetic theory of gases under the assumption of a perfect (ideal) gas.
