The answer is Photosynthesis!
Answer : The average atomic mass of an element X is, 63.546 amu
Solution : Given,
Mass of isotope X-63 = 62.9296 amu
% abundance of isotope X-63 = 69.15% = 0.6915
Mass of isotope X-64 = 64.9278 amu
% abundance of isotope X-64 = 30.85% = 0.3085
Formula used for average atomic mass of an element X :
![\text{ Average atomic mass of an element X}=\sum[(62.9296\times0.6915)+(64.9278\times 0.3085)]](https://tex.z-dn.net/?f=%5Ctext%7B%20Average%20atomic%20mass%20of%20an%20element%20X%7D%3D%5Csum%5B%2862.9296%5Ctimes0.6915%29%2B%2864.9278%5Ctimes%200.3085%29%5D)
Therefore, the average atomic mass of an element X is, 63.546 amu
A thing that is composed of tow or more seperate elements
The Nazca plate is converging with the South American plate.
Explanation:
The Andes Mountains are formed as a result of the convergent of the Nazca plate and the South American plate.
This mountain range typifies the geology and geography of the South American continent.
- Along this convergent margin, one plate subducts beneath the other.
- The oceanic plate due to its density goes into the mantle.
- The causes the continent riding to obduct and be forced.
- With rising magmatic bodies beneath, the continent further pushes up to form the Andes ranges.
