Using the equation, 4fe + 3o2 imported asset 2fe2o3, if 111.6 g of iron react, what mass of oxygen was consumed? 32.0 g 48.0 g 96.0 g 111.6 g

48.0 g

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.

To calculate the number of moles, we use the equation:

According to stoichiometry:

4 moles of iron react with 3 moles of oxygen

thus 2 moles of iron will react with = moles of oxygen

Mass of oxygen=

Thus 48 g of oxygen were consumed.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
