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

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
