Answer: 9.9 grams
Explanation:
To calculate the moles, we use the equation:
a) moles of
b) moles of
According to stoichiometry :
1 mole of combine with 1 mole of
Thus 0.33 mole of will combine with =
mole of
Thus is the limiting reagent as it limits the formation of product.
As 1 mole of give = 1 mole of
Thus 0.33 moles of give =
of
Mass of
Thus theoretical yield (g) of produced by the reaction is 9.9 grams
