Question #26588

how many atoms of oxygen are present in 1 mole of oxygen?

Expert's answer

To calculate the number of molecules we need to:

For a start let us recall the formula for calculating the number of particles:

n = N/NA

n - the number of moles

N - number of particles

NA - constant Аvogadro (6.02*10^23 mol-1)

From this :

N = NA*n

N =& 6.02*10^23 mol-1 * 1 mol = 6.02*10^23 molecules

Answer:

& Number of molecules = 6.02*10^23 molecules
