On another planet, the isotopes of titanium have the following natural abundances.
Isotope 46Ti Abundance 70.900% Mass(amu) 45.95263
Isotope 48Ti Abundance 10.000% Mass(amu) 47.94795
Isotope 50Ti Abundance 19.100% Mass(amu) 49.94479
What is the average atomic mass of titanium on that planet?
I got 46.9 amu but it is wrong.
I'm sorry I posted the right answer to the wrong question
46.627 u is the correct answer
There are three isotopes of titanium present, 46Ti, 48Ti, and 50Ti, so there are three terms in the weighted average equation.
average atomic mass=(45.95263 u×74.500%100%)+(47.94795 u×17.200%100%)
+(49.94479 u×8.300%100%)
average atomic mass=46.627 u
46.83
Remember that while calculating you are not suppose to approximate not until you arrive at your final answer.
