On another planet, the isotopes of titanium have the given natural abundances. Isotope Abundance Mass (u)
46Ti 77.100% 45.95263
48Ti 17.100% 47.94795
50Ti 5.800% 49.94479

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

46.525 u

Explanation:

From the question given above, the following data were obtained:

Isotope A (⁴⁶Ti)

Abundance (A%) = 77.100%

Mass of A = 45.95263 u

Isotope B (⁴⁸Ti):

Abundance (B%) = 17.100%

Mass of B = 47.94795 u

Isotope C (⁵⁰Ti):

Abundance (C%) = 5.800%

Mass of C = 49.94479 u

Average atomic mass =?

The average atomic mass of titanium can be obtained as follow:

Average = [(Mass of A × A%)/100] + [(Mass of B × B%)/100] + [(Mass of C × C%)/100]

= [(45.95263 × 77.1)/100] + [(47.94795 × 17.1)/100] + [(49.94479 × 5.8)/100]

= 35.429 + 8.199 + 2.897

= 46.525 u

Therefore, the average atomic mass of titanium is 46.525 u
