Jessica has 12.7 moles of a compound for an experiment. how many particles of the compound does she have? a. 2.11 × 1023 b. 4.74 × 1023 c. 7.65 × 1023 d. 4.74 × 1024 e. 7.65 × 1024

The number of particles  that  are in 12.7  moles of  compound that Jessica had is     7.65 x10^24 particles  of compound ( answer E)

    Calculation

The number  of particles are calculated  using the Avogadro's Principle  constant.

             what about 12.7 moles  of  compound=   ?  particles\

   by use of  cross multiplication

 N.b moles and moles cancels each  other
