Answer : The mass of product produced if the reaction occurred with a 70.5 percent yield will be, 20.67 grams.
Explanation : Given,
Mass of P = 25 g
Mass of = 25 g
Molar mass of P = 30.97 g/mole
Molar mass of = 71 g/mole
Molar mass of = 208.24 g/mole
First we have to calculate the moles of and .
Now we have to calculate the limiting and excess reagent.
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 5 moles of react with 2 moles of
So, 0.352 moles of react with moles of
That means, in the given balanced reaction, is a limiting reagent and it limits the formation of products and is an excess reagent because the given moles are more than the required moles.
Now we have to calculate the moles of .
As, 5 moles of react with 2 moles of
So, 0.352 moles of react with moles of
Now we have to calculate the mass of .
Now we have to calculate the mass of product produced (actual yield).
Therefore, the mass of product produced if the reaction occurred with a 70.5 percent yield will be, 20.67 grams.
