The dalton or unified atomic mass unit (symbols: Da or u) is a non-SI unit of mass widely used in physics and chemistry. It is defined as 1⁄12 of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state and at rest. The atomic mass constant, denoted mu, is defined identically, giving mu = m( C)/12 = 1 Da. This unit is commonly used in physics and chemistry to express the mass of atomic-scale objects… Web14) What is the mass (in grams) of 6.022x1023 atoms of 12C? 15) What is the mass (in grams) of one molecule of carbon dioxide which has one 12C atom and two 16O atoms, 12C16O2? 16) Indicate whether the following statement is true or false and explain your reasoning. An 18O atom contains the same number of protons, neutrons, and electrons.
