Question

On another planet, the isotopes of titanium have the given natural abundances. Isotope Abundance Mass (u) 46Ti 73.800% 45.95263 48Ti 18.900% 47.94795 50Ti 7.300% 49.94479 What is the average atomic mass of titanium on that planet? average atomic mass =

also round to the correct amount of Significant Figures

Answer 1

Solution: Equation: Isotopemassx Abundance percent Average atomic mass = Substitute Average atomic mass =(45.95263 ux 73.800)+( 47.94795 ux !.000)+(49.94479ux 72000) Average atomic mass=46.621173 u Average atomic mass=46.62u| The final answer is rounded to four significant figures because the given percent of abundance has the fewest significant figures (four).
