    I have been asked:

    "how much lead (IV) oxide would be required to make up 150 grams of sodium oxide?

    The equation is PbO2+2Na2SO4--> 1 Pb(SO4)2 +2 Na2O

    And I am lost.

    First off, I worked out the number of moles for the sodium oxide which I found to be:

    150 g (mass) / 62g (gfm) =2.42 moles.

    I want mass of PbO2; ergo M = N x gfm
    So I figured 239.2 (gfm of
    But eh that's entirely wrong

    Where HAVE I went wrong......?

    The Answer SHOULD be: 289 grams :\
