Simple Mixture 1
In this example, items 9 and 10 are relatively easy to calculate because all of the ethanol is coming from one source (see the first line in item# 13) and the yield is 100% (simple mixture).
Step 3. To calculate item 9, you would divide 0.979 gallons of absolute ethanol by the yield (9.5 gallons):
0.979 gallons ÷ 9.5 gallons = 0.103 or 10.3%
For this formula, items 9 and 10 are calculated the same way. The tolerance is applied only to item 10 as described in the tolerance table for a simple mixture.
