How many atoms are in 5.5 moles

33.11 x 10²³atoms

= 3.311 x 10^24 atoms

Explanation:

The number of atoms present in a given number of moles of a substance is given by;

Number of moles, n * Avogadro's number, NA

We are given number of moles, n = 5.5 moles

Avogadro's number, NA = 6.02 * 10²³

Therefore, number of atoms present in 5.5 moles

= 5.5 x 6.02 * 10²³

= 33.11 * 10²³

= 3.311 * 10^24 atoms

Answer: 3.312177825e+24 Atoms
