1. Thus the molecular mass of each member differs by 14 atomic mass units . 2. The Dalton ( Da ) is another name for the unified atomic mass unit . 3. Monoisotopic mass is typically expressed in unified atomic mass units ( u ), also called daltons ( Da ). 4. :: I expect you want the molecular mass in Daltons or " atomic mass units ", not grammes. 5. This complicates the study of molecules interacting with high atomic mass unit atoms, such as transitional metals and their catalytic properties. 6. A possible candidate are interferometry experiments with heavy molecules, which currently reach masses up to 10, 000 atomic mass units . 7. It is denoted with symbols " u " ( for unified atomic mass unit ) or " Da " ( for dalton ). 8. The relative molecular mass may be converted to an absolute value by multiplying it by the atomic mass unit ( 1 u ) in picograms. 9. For comparison, the "'atomic mass "'of a carbon-12 atom is exactly 12 unified atomic mass units . 10. JADE-I can measure ions from 1 to 50 atomic mass units ( AMU ), with the ability to discern Sulfur from Oxygen.
