    a.) 2 mol S + 3 mol O2 ----> 2 mol SO3
    b.) 2 atoms S + 3 molecules O2 ----> 2 molecules SO3
    c.) 2 g S + 3 g O2 ----> 2 g SO3
    d.)none of the above

    Do you understand that different elements have different atomic masses?

    coefficients symbolize the number of moles so A would be correct.

    Then im not 100% sure about B cause the molecules seem to be right but im not sure about the atoms of S and if that is a correct interpretation.

    And for C, I don't think that the coefficients can stand for grams cause there are multiple grams in a mole.

    How is my thinking?
