Answer:
The mass of an object is the same no matter where it is, but the weight of an object changes with the location of that object. For example, the weight of an object on the Moon is 1/6th that of the same object on Earth, while the mass of that object is exactly the same in both places.

Answer:
70.202 amu
Explanation:
From the question given above, the following data were obtained:
Isotope A:
Abundance (A%) = 39.9%
Mass of A = 69 amu
Isotope B:
Abundance (B%) = 60.1%
Mass of B = 71 amu
Average atomic mass =?
The average atomic mass of the element can be obtained as follow:
Average atomic mass = [(Mass of A × A%)/100] + (Mass of B × B%)/100]
= [(69 × 39.9)/100] + [(71 × 60.1)/100]
= 27.531 + 42.671
= 70.202 amu
Therefore, the average atomic mass of the element is 70.202 amu
The group is called the noble gas i think
