    Answer:

    8.72 × 10^5 moles

    Explanation:

    To find the number of moles in 5.25 x 10^29 molecules of sucrose, we divide the number of molecules by Avagadro constant (6.02 × 10²³ molecules). That is;

    no. of moles = no. of molecules ÷ 6.02 × 10²³ molecules

    In this case of sucrose, no of moles contained is as follows;

    5.25 × 10^29 ÷ 6.02 × 10²³

    5.25/6.02 × 10^ (29-23)

    0.872 × 10^6

    = 8.72 × 10^5 moles
