    c (C12H22O11) = 342.3 g/mol

    454 g / (342.3 g/mol) = 1.326 mol

    1.326 mol * 6.022*10^23 molecules/mol = 7.985·10^23 molecules

    I mole of sucrose = 6.02 X 10²³ molecules

    454 grams of sucrose = ?

    To find the number of moles of sucrose in 454grams:

    no of moles = mass/molarmass

    mass = 454g

    molar mass of sucrose C12H22O11 = (12x12) + (1x22) + (16x11)

    =144+22+176

    342g/mol

    no. of moles = 454/342

    = 1.33mole

    since 1 mole of sucrose = 6.02 X 10²³ molecules

    1.33 mole of sucrose = 1.33 X 6.02 X 10²³

    = 8.01 X 10²³ molecules
