Question

on another planet, the isotopes of titanium have the given natural abundances. isotope abundance mass (u) ^46ti 71.800% 45.95263 ^48ti 13.700% 47.94795 ^50ti 14.500% 49.94479 what is the average atomic mass of titanium on that planet? average atomic mass:

Explanation:

Step1: Convert abundances to decimals

$71.800\% = 0.718$, $13.700\%=0.137$, $14.500\% = 0.145$

Step2: Calculate contribution of each isotope

For $^{46}$Ti: $0.718\times45.95263$
For $^{47}$Ti: $0.137\times47.94795$
For $^{48}$Ti: $0.145\times49.94479$

Step3: Sum up the contributions

$0.718\times45.95263+0.137\times47.94795 + 0.145\times49.94479$
$=33.09399834+6.56886915+7.24109455$
$=46.90396204\approx46.90$

Answer:

$46.90$
