Suppose that there were two natural isotopes of Tin (Sn). Sn-110 had a mass of 110.013 amu and Sn-111 had a mass of 111.009 amu. Calculate percent abundance for each isotope if the average atomic mass of tin is 110.1 amu.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
