Have you ever wondered how many atoms are in a drop of water or how many molecules are in a single droplet? The answer depends on your definition of thevolumeof a droplet of water. Water drops vary dramatically in size, so this starting number defines the calculation. The rest of it is...
atoms in the Sun, we would need to divide the mass of the sun by the molar mass of the hydrogen atom and multiply that by Avogadro’s number. Avogadro’s number is the number of elementary particles, such as molecules, atoms, compounds, etc. per mole of a substance; this will give ...
1. Definition of a Mole: A mole is a unit that measures the amount of substance. It is defined as the amount of substance that contains as many entities (atoms, molecules, ions, etc.) as there are in 12 grams of carbon-12.2. Formula: The relationship between the number of moles (...
