How many atoms are in 2.12 moles of C₂H₆

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

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )
