Question

On a mission to a newly discovered planet, an astronaut finds gallium abundances of 61.29% for 69Ga and 39.71% for 71Ga . What is the atomic mass of gallium for this location?
The mass of 69Ga is 68.7200amu . The mass of 71Ga is 70.9200amu .

Answer 1

(exact weight of isotope #1) (abundance of isotope #1) + (exact weight of isotope #2) (abundance of isotope #2) = average atomic weight of the element

Answer 2

can you hel ,e as this is my first time doing this, just plug in numbers for me

Answer 3

is it 7028.082

Answer 4

68.70*61.29+39.71*70.90=

Answer 5

finally divide it by 100

Answer 6
