In 1803,John Daltonsuggested a way to express relative atomic mass in terms of hydrogen-1 (protium). Subsequently,Wilhelm Ostwaldsuggested expressing the relative atomic mass as one-sixteenth the mass ofoxygen. But, when isotopes and isotopic oxygen were discovered, it created confusion about how ...

methane atomic mass = 16.043 This value may be reported as a decimal number or as 16.043 Da or 16.043 amu. Notethe number of significant digitsin the final value. The correct answer uses the smallest number of significant digits in the atomic masses, which in this case is the number in ...
