# Na2B4O7 is the overall limiting reagent in this problem.

Not if it has a unit attached to it or not.3) Determine how many moles of the excess reagent is used up when the limiting reagent is fully consumed:

the mole ratio we desire is 2/17 (C6H10 to O2)2/17 equals x / 1.406x = 0.1654 mol of C6H10 consumed
4) Determine grams of C6H10 remaining:
0.426 mol minus 0.1654 mol = 0.2606 mol of C6H10 remaining0.2606 mol times 82.145 g/mol = 21.4 g remaining (to three sig figs)
Example #4: (a) What mass of Al2O3 can be produced from the reaction of 10.0 g of Al and 19.0 g of O3?

### number of reaction equivalents is the "limiting reagent."

The substance that has the smallest answer is the limiting reagent.Let's say that again:

to find the limiting reagent, take the moles of each substance and divide it by the coefficient of the balanced equation.

The quantity in the denominator (2.5 g) represents the theoretical yield of aspirin based on the moles of salicylic acid and acetic anhydride used in the synthesis.

The yield of the reaction is based on the limiting reagent, also termed as limiting reactant, which determines the extent of the reaction before the reaction is complete.

## For the synthesis of aspirin from ..

Consider the reaction:

2 Al + 3I2 ------> 2 AlI3
Determine the limiting reagent and the theoretical yield of the product if one starts with:
a) 1.20 mol Al and 2.40 mol iodine.
b) 1.20 g Al and 2.40 g iodine
c) How many grams of Al are left over in part b?

1) Determine the limiting reagent:

butane: 28 / 1 = 28
oxygen: 228 / 6 = 38Butane is the limiting reagent.
2) Determine how much oxygen reacts with 28 C4H8 molecules:
the butane:oxygen molar ratio is 1:628 x 6 = 168 oxygen molecules react
3) Determine excess oxygen:
228 - 168 = 60
Here's aother way to consider this:
The 38 above means that there are 38 "groupings" of six oxygen molecules.
