The two naturally occurring isotopes of bromine are 81Br (80.916 amu, 49.31%) and 79Br (78.918 amu,...
The two naturally occurring isotopes of bromine are 81Br (80.916 amu, 49.31%) and 79Br (78.918 amu, 50.69%). The two naturally occurring isotopes of chlorine are 37Cl (36.966 amu, 24.23%) and 35Cl (34.969 amu, 75.77%). Bromine and chlorine combine to form bromine monochloride, BrCl. What are the masses of the four different BrCl molecules? Express the masses in atomic mass units using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.

Most elements occur naturally as a mix of different isotopes. An element's atomic mass is the weighted average of the isotope masses. In other words, it is an average that takes into account the percentage of each isotope. For example, the two naturally occurring isotopes of boron are given here The atomic mass of boron is calculated as follows: (10.0 times 0.199) + (11.0 times 0.801) = 10.8 amu Because the heavier isotope is more abundant the atomic mass a...

The two isotopes of uranium, 235U (atomic mass 235.04 amu) and 238U (atomic mass 238.05 amu), can be separated by a gas-diffusion process by combining them with fluorine to make the gaseous compound UF6 (atomic mass of fluorine is 18.998 amu). Part A Calculate the ratio of the rms speeds of these molecules for the two isotopes, at constant T. Express your answer using five significant figures.
