    Answer:

    moles = no. of molecules / Avogadro’s number

             = 2.26 x 10^33 / 6.022 x 10^23

             = 3752906011

    Round to significant figures which is 3 = 3.75 x 10^9 mol

    Explanation: The formula for finding how many moles of a substance when given the amount of molecules is: moles = number of molecules / Avogadro’s number
