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

Explanation:

Step1: Convert abundances to decimals

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

Step2: Calculate the contribution of each isotope

For $^{46}\text{Ti}$: $0.718\times45.95263 = 33.09399834$
For $^{48}\text{Ti}$: $0.137\times47.94795=6.56886915$
For $^{50}\text{Ti}$: $0.145\times49.94479 = 7.24199455$

Step3: Find the average atomic mass

$33.09399834 + 6.56886915+7.24199455=46.90486204\approx46.905$

Answer:

$46.905$
