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

Conversions aren't bad until you have to deal with the cubed and squared versions of them!! Remember that there are 100 cm in 1 meter. If that be the case, then there are 100cm*100cm*100cm (100cm^3) in m*m*m (1 meter cubed). We will use that in our conversion then:
. The cm^3 cancels out leaving m^3 over m^2 which is what we want. Doing the math now we get
, or
98.4252<span> inches is the exact so about 98 inches</span>
