How many atoms are there in 2 moles of sodium?

If we have 2 mol of Na atoms, we have 2 × (6.022 × 10 23) Na atoms, or 1.2044 × 10 24 Na atoms.

How many atoms are there in sodium?

Then, multiply the number of moles of Na by the conversion factor 6.02214179×1023 atoms Na/ 1 mol Na, with 6.02214179×1023 atoms being the number of atoms in one mole of Na (Avogadro’s constant), which then allows the cancelation of moles, leaving the number of atoms of Na.

How many atoms are in 3 moles of sodium?

3 mol Na × (6.022×10^23 atoms Na/1mol Na) = 1.807×10^24 atoms Na.

How do you find number of atoms?
