    Answer

    Number of molecules: 8.089*1022 molecules

    Explanation

    The formula for this question is

    Number of molecules

    = Number of moles * 6.02x1023

    Since,

    the number of moles = given mass/formula mass

    Here,

    Formula mass of sucrose = 342.3 g/mol

    Given mass = 46g

    Therefore,

    The number of molecules = given mass*6.02*1023/

    Formula mass

    =46*6.02*1023/342.3

    =8.089*1022 molecules.
