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

Answer:
Michelle bought a pack of crayon for $3.25
Step-by-step explanation:
Number of packs = 5
The cost of a pack of crayons =
(Cost of 5 packs of crayon) / (number of packs of crayons)
The cost of a pack of crayons = ($16.25 ) / 5
The cost of a pack of crayons = $16.25 / 5
The cost of a pack of crayons = $3.25
Just convert the greater value (i.e. meters) to the smaller value
