Answer 2

The dalton or unified atomic mass unit(symbols: Da or u) is a 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.[1][2] The atomic mass constant, denoted mu, is defined identically, giving mu = m(12C)/12 = 1 Da.[
