    Answer: Average atomic mass of titanium on that planet is 46.52

    Explanation:

    Mass of isotope Ti-46 = 45.95263

    % abundance of isotope Ti-46  = 77.600 % = \frac{77.600}{100}=0.776

    Mass of isotope Ti- 48= 47.94795

    % abundance of isotope Ti-48 = 16.100%= \frac{16.100}{100}=0.161

    Mass of isotope Ti- 50 = 49.94479

    % abundance of isotope Ti-50  = 6.300%= \frac{6.300}{100}=0.063

    Formula used for average atomic mass of an element :

    \text{ Average atomic mass of an element}=\sum(\text{atomic mass of an isotopes}\times {{\text { fractional abundance}})

    Z=\sum[(45.95263 \times 0.776)+(47.94795 \times 0.161)+(49.94479\times 0.063)

    Z=46.52

    Average atomic mass of titanium on that planet is 46.52
