Bromine has two stable isotopes: 79Br and 81Br with masses of 78.9183371 amu and 80.9162906 amu. If the average atomic mass for Bromine on Earth is 79.904 amu, what is the mass of 79Br in a 10.0 g sample? Hint: Set the abundance of the 79Br isotope equal to x. Then the abundance of the other isotope will equal 1−x. Your answer should have three significant figures, so round to the nearest hundredth.
