Calculate the number of atoms in 3 mol helium
To calculate the number of atoms in 3 mol of helium, you need to use Avogadro's number.
Avogadro's number is 6.022 x 10^23 atoms/mol.
Therefore, the number of atoms in 3 mol of helium is:
3 mol * (6.022 x 10^23 atoms/mol) = 1.8066 x 10^24 atoms
To calculate the number of atoms in 3 mol of helium, we can use Avogadro's number, which is 6.022 x 10^23 atoms/mol.
First, we need to multiply the number of moles by Avogadro's number to find the number of atoms:
Number of atoms = Number of moles x Avogadro's number
Number of atoms = 3 mol x (6.022 x 10^23 atoms/mol)
Number of atoms = 1.8066 x 10^24 atoms
Therefore, there are approximately 1.8066 x 10^24 atoms in 3 mol of helium.
