Question

On another planet, the isotopes of titanium have the given natural abundances.

IsotopeAbundanceMass (u)
46Ti	75.200%	45.95263
48Ti	10.900%	47.94795
50Ti	13.900%	49.94479

What is the average atomic mass of titanium on that planet?

Answer 1

Take the weighted average as follows:

(0.75200 * 45.95263) + (0.10900 * 47.94795) + (0.13900 * 49.94479) = 34.556 + 5.2263 + 6.9423 = 46.725
