    The second mole question was how much HI will be made with 43.5 g of H2, it was to be solved like this 2g of H2-------256 g of HI 45.3g --------- z then we will cross multiply like this 2z = 256 x 45.3 z = 5798.4g EDITED

    when we write an equation for a reaction we never write the catalyst in the equation, and aftr the reaction the mass of the catalyst remains same, this shows that catalysts dont take part in the rection themselves, but only speed up the reaction!!
