Who gave Avogadro number?

physicist Jean Baptiste Perrin
The term “Avogadro’s number” was first used by French physicist Jean Baptiste Perrin. In 1909 Perrin reported an estimate of Avogadro’s number based on his work on Brownian motion—the random movement of microscopic particles suspended in a liquid or gas.

How do you zoom in Avogadro?

Navigation. You can zoom in/out using the scroll wheel on your mouse or holding down the middle mouse button and moving the mouse cursor up/down. You can rotate the view by holding down the left mouse button and moving the mouse cursor.

How do you remove hydrogen from Avogadro?

Right clicking on the atom will delete it. Left clicking and dragging the mouse will generate a bond to another carbon atom. Different elements can be selected from the Element drop down menu. Typing the atomic symbol (e.g., “A-s” for Arsenic) is a shortcut for changing the selected element.

How do I add a bond to Avogadro?

Bonds are added by left clicking on a bond that has already been created. Right clicking on a bond deletes the bond, and the atom it’s bonded to.

Why did Avogadro create the mole?

The goal of this definition was to make the mass of a mole of a substance, in grams, be numerically equal to the mass of one molecule relative to the mass of the hydrogen atom; which, because of the law of definite proportions, was the natural unit of atomic mass, and was assumed to be 1/16 of the atomic mass of oxygen …
