By chemical means originally and subsequently by other means, it has been found that the relative atomic masses are: Zn 65.37 and S 32.06. [The basis of the scale is that 12C is 12].

hey.. i just want to know wth 12C is ...
btw... i have no chemistry knowledge.. lol...

i think that this is talking about moles... remember that one mole is exactly 12 grams of carbon 12 (year 11 text book)

It's referring to Carbon-12 (the most common isotope of Carbon) -- 1 mole of carbon-12 = 12grams of carbon-12
