Answer:

1.31×10^-16moles

Explanation:

If 1 mole of carbon contains 6.02×10^23 carbon atoms (Avogadro's number)

X moles of carbon contain 7.87×10^7 carbon atoms

X = 7.87×10^7/6.02×10^23

X= 1.31×10^-16moles

Note that 1 moles of any substance contains Avogadro's number of elementary entities (atoms, ions, molecules etc)

Resonance occurs in cases where two or more Lewis structures with identical arrangements of atoms but different distributions of electrons can be written.
