How many atoms are there in 7.2 mol neon? A.) 4.3 x 10^24 atoms
B.) 3.5 x 10^24 atoms
C.) 5.8 x 10^-24 atoms
D.) 43.3 atoms
E.) 3.5 x 10^-24 atoms

A) 4.3 × 10²⁴ atoms

Explanation:

Step 1: Given data

Moles of neon: 7.2 moles

Step 2: Calculate the number of atoms present in 7.2 moles of neon

In order to convert moles to toms, we need a conversion factor. In this case, we will use Avogadro's number: there are 6.02 × 10²³ neon atoms in 1 mole of neon atoms.

7.2 mol × 6.02 × 10²³ atoms/mol = 4.3 × 10²⁴ atoms
