Answer:
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
