Answers

  1. The 12.7 moles of a compound contain 7.65 x 10 24 particles.
    Avogadro’s number is the number of units, which could be atoms, particles, electrons, molecules, or even ions, per mole of a substance. The value of Avogadro’s number is 6.02214076 x 10 23.
    To answer this question, we will multiply the given moles of the compound to Avogadro’s number, which will have a unit of particles/mol.
    Number of particles of given compound = number of moles * Avogadro’s number in particles/mol = 12.7 moles * 6.02214076 x 10 23 particles/moles
    Number of particles of given compound = 7.65 x 10 24 particles
