    2.01*10²² molecules are in 0.0334 moles of CO₂

    Explanation:

    The relation we must to know, is that one mol is occupied by 6.02*10²³ molecules.

    In order to calculate the number of dioxide molecules we can do this conversion → from moles to number of molecules

    0.0334 mol. 6.02*10²³ molecules / 1 mol = 2.01*10²² molecules

    We can also propose a rule of three:

    1 mol contains 6.02*10²³ molecules

    0.0334 moles will be contained by (0.0334. 6.02*10²³) / 1 = 2.01*10²²
