multiply that number by avagadros number, 6.02x10^23
avagadros number
As in number? No of atoms = avagadros number (6.02X10^23) times number of mole of atoms
Avagadros number - The number of molecules/element that are found in one mole of the substance
A mole is equal to 6.022 x 1023. This number is called Avagadros number. A mole is generally abreiviated as "n".
the number of atoms in a certain space its really of any significance , u can do all the everythong without it
A mole (mol). You can convert to kilograms using Avagadros number.
Avogadro's number is a constant that represents the number of particles (atoms, molecules) in one mole of a substance. It is approximately equal to 6.022 x 10^23 particles per mole. The unit for Avogadro's number is mol^-1.
By particles, I assume you mean atoms. Firstly, you divide mass by molecular mass to get moles. Then multiply moles by avagadros number to get amount of atoms
You divide the 6.073 by 6.022x1023 (avagadros number) to get the moles, then multiply by molecular mass (18) to get mass in grams
very roughly 5 moles...avagadros number = 6.022 x 1023 just devide 30 by this number
