Answer:
1.28 x 10²⁴atoms
Explanation:
Given parameters:
Number of moles of C₂H₆ = 2.12moles
Unknown:
Number of atoms = ?
Solution:
A mole of a substance is used to quantity the number of atoms or other particles in a substance.
1 mole of a substance = 6.02 x 10²³ atoms
To solve this problem;
2.12 moles of the C₂H₆ will contain 2.12 x 6.02 x 10²³ atoms
= 1.28 x 10²⁴atoms
