    Answer:

    The ratio of atoms of potassium to atoms of oxygen is  2:1

    Explanation:

    As the equation given is :

    4K + O_2 -----> 2K_2O

    The product formed is 2 moles of potassium oxide .

    Amount of potassium atom in the potassium oxide  is 2 atoms of potassium and amount of oxygen atom present here is 1 atom of oxygen .

    But we have 2 moles of potassium oxide . So, the potassium and oxygen atoms will be multiplied by 2 .

    Hence , we get 4 atoms of potassium and 2 atoms of oxygen .

    Ratio of potassium to oxygen atoms is –   4:2

    Therefore ,   2:1
