Answer: 34.4 g
Explanation:
As is in excess,
is the limiting reagent and thus it will limit the formation of products.
According to stoichiometry:
2 moles of hydrogen produce = 1 mole of
2.5 moles of hydrogen produce = of
Mass of
But as % yield is 86%, mass of produded is
Thus 34.4 g of is produced.
