Molecular weight: Mass of a molecule of a substance, based on 12 as the atomic weight of carbon-12.

And I thought molecular weight sounded much less nerdy than molar mass.

The etching results show that with certain mole percentages of adipic acid and other things being equal, the etched ridge structures possess larger ridge depths and more vertical ridge sidewalls .

The normality of a solution of a triprotic acid is three times its molarity .

Your goal is to report the molarity of the hydrochloric acid and the molarity of the phosphoric acid in the mixture, with their uncertainties.
