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

Answer : The average atomic mass of Ti is, 46.86 amu

Explanation :

Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.

Formula used to calculate average atomic mass follows:

As we are given that,

Mass of isotope = 45.95263 amu

Percentage abundance of isotope = 70.300 %

Fractional abundance of isotope = 0.70300

Mass of isotope = 47.94795 amu

Percentage abundance of isotope = 13.700 %

Fractional abundance of isotope = 0.13700

Mass of isotope = 49.94479 amu

Percentage abundance of isotope = 16.000 %

Fractional abundance of isotope = 0.16000

Now put all the given values in above formula, we get:

Therefore, the average atomic mass of Ti is, 46.86 amu

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
