How do you calculate number of atoms?
# of atoms = N * (density) * volume / (Molecular Weight). N is a constant called Avogadro's number and its equal to 6.022*1023 atoms/mole. It can also be molecules per mole. In the above formula density times volume is just the mass.
How many atoms are in h2o?
three atoms A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom. That's why water is sometimes referred to as H2O.

How many grams is an atom?
The mass of a single carbon atom is 1.994 x 10-23 g. The mass of a single atom is an extremely small number! This is why chemists use Avogadro's number.
How many electron does Li+ have?
2 Therefore, the electrons in a Lithium ion need to be 3 but lithium as a metal donates the electron. So to have a+1 charge, Lithium must have lost an ion. Therefore the number of electrons in Lithium is 2.
How many electrons are in a Li+ ion?
However, in this question we are being asked the electrons in a lithium ion. Lithium, as a metal, donates electrons and so must have lost an ion in order to have a +1 charge. Therefore, the number of electrons must be 2.
How many atoms are in a mole?
6.022 × 1023 atoms The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro's Number (6.0221421 x 1023).
How many atoms are in a mole calculator?
A mole of any substance contains Avogadro's number (6.02 × 1023) of atoms. To convert the number of atoms to number of moles we need to use the conversion factor: number of atoms x 1 mole / 6.023 x 1023 atoms.
How do I calculate moles?
How to find moles? Measure the weight of your substance. Use a periodic table to find its atomic or molecular mass. Divide the weight by the atomic or molecular mass.
