Most lactic acid solutions are 88% w/w. One mL of an 88% solution has a weight of 1.3 g and so contains 0.88*1.3 = 1.14 grams of the acid

Wouldn't 1ml of an 88% solution contain .88g of the solute? If I remember my high school chemistry ( 1965- a long time ago) , to make 100ml of an 88% solution we would weigh 88g of solute and dissolve in enough distilled water to make 100ml.

To make an 88% w/w solution you would put 88 grams of lactic acid in a beaker and add 12 grams of DI water. This would give you 100/1.3 mL of solution.

Right U R! Lactic Acid 88% is w/w not w/v. Thanks for the heads up. Now I need to recalc my Ascorbic acid dihydrate grams to Lactic Acid 88% mils equivalency
