How many moles of sucrose are in 5.25x10^29 sucrose molecules

In order to find the answer to the question, there has to be an understanding of what Avogadro's Number is. Avogadro's Number (6.02 × 10²³ particles/mole) represents the number of particles (molecules/atoms) that are in one mole of a substance.

Thus, if 1 mole contains 6.02 × 10²³ particles
Then let x moles contain 5.25 × 10²⁹ particles

⇒  (6.02 × 10²³) x  =  5.25 × 10²⁹
⇒                       x  =  (5.25 × 10²⁹)  ÷  (6.02 × 10²³)
⇒                       x  =  8.72 × 10⁵ moles

Thus the number of moles of sucrose in 5.25x10^29 sucrose molecules  is
8.72 × 10⁵ moles
