    4.10 g C12H22O11 * (1 mol / 342.2965 g) * (6.022x10^23 / 1 mol) = 7.2107077x10^21 molecules = 7.21x10^21 molecules

    Convert grams to moles using the molar mass (g/mol).

    Use Avogadro's constant (6.022x10^23) to get the quantity of molecules from the amount of moles.

    Revise answer to have the correct number of significant figures (the smallest amount of digits in any number in the problem is the amount of significant figures your answer should have).
