Question

how many atoms are present in 2.0 moles na? 2.0 moles na 1.2 x 10^{24} atoms na 3.3 x 10^{22} atoms na 6.02 x 10^{23} atoms na 3.3 x 10^{-24} atoms na

Explanation:

Step1: Recall Avogadro's number

1 mole = $6.02 \times 10^{23}$ atoms

Step2: Calculate total atoms

Atoms = moles × Avogadro's number
$2.0 \times 6.02 \times 10^{23} = 1.204 \times 10^{24} \approx 1.2 \times 10^{24}$

Answer:

1.2 x 10²⁴ atoms Na
