To find the number of atoms in 0.0019 mol of zirconium, we need to use Avogadro's number, which is the number of particles (atoms, molecules, ions) in one mole of any substance.
Avogadro's number is approximately 6.022 x 10^23 particles/mol.
To find the number of atoms in 0.0019 mol of zirconium, we can use the following formula:
Number of atoms = moles x Avogadro's number
Number of atoms = 0.0019 mol x 6.022 x 10^23 particles/mol
Number of atoms = 1.1438 x 10^21 atoms
Therefore, there are approximately 1.1438 x 10^21 atoms in 0.0019 mol of zirconium.
