When I do out the math I get 2.7 instead of 2.8 for the constant in the original post. Am I missing anything (haven't had chemistry since high school), or did Baums round the molar mass ratio to 2 from 1.875.
O2 = 32 g/mol
Acetic acid = 60 g/mol
It takes one molecule of O2 to produce 1 molecule of acetic acid.
60/32 = 1.875 g of acetic acid for each gram of oxygen.
1 cc of O2 weighs .00143 mg
.00143*1.875 = 2.68 mg of acetic acid
2.68 mg/l = 2.68 ppm
