    Hello!

    How many grams are in 3.3 X 10^23 molecules of N2I6

    By the Law of Avogrado, we know that for each mole of a substance we have 6.02x10²³ molecules, then:

    1 mol --------------- 6.02x10²³ molecules

    y mol --------------- 3.3x10²³ molecules

    Product of extremes equals product of means

    6.02*10^{23}*y = 1*3.3*10^{23}

    6.02*10^{23}y = 3.3*10^{23}

    y = \dfrac{3.3}{6.02}*10^{23-23}

    y \approx 0.548*10^0

    y \approx 0.548*1

    \boxed{y \approx 0.548\:mol}

    Now, let's find the mass (how many grams of N2I6) , datos:

    Molar Mass N2I6 = 2*(14u) + 6*(126.9u) = 28 + 761.4 = 789.4 g/mol

    If:  

    1 mol --------------- 789.4 g  

    0.548 mol ------------ y g  

    Product of extremes equals product of means

    1*y = 0.548*789.4

    y = 432.5912 \to \boxed{\boxed{y \approx 432.6\:grams\:of\:N_2I_6}}\:\:\:\:\:\:\bf\red{\checkmark}
