Answer: 28.1 amu
Explanation:
Mass of isotope 1 = 27.98 amu
% abundance of isotope 1 = 92.21% = 
Mass of isotope 2 = 28.98 amu
% abundance of isotope 2 = 4.70% = 
Mass of isotope 3 = 29.97 amu
% abundance of isotope 2 = 3.09% = 
Formula used for average atomic mass of an element :
![A=\sum[(27.98 )\times 0.922+(28.98)\times 0.047+(29.97)\times 0.0309]](https://tex.z-dn.net/?f=A%3D%5Csum%5B%2827.98%20%29%5Ctimes%200.922%2B%2828.98%29%5Ctimes%200.047%2B%2829.97%29%5Ctimes%200.0309%5D)
Therefore, the average atomic mass of silicon is 28.1 amu
Answer:
The answer to your question is 8.75 x 10 ²⁵ atoms of Magnesium
Explanation:
Data
Atomic mass of Magnesium = 24.31 g
Atoms of magnesium = 3.60 x 10²⁴
Process
Solve this porblem using a rule of three
1 atom of Magnesium --------------- 24.31 g
3.60 x 10²⁴ ---------------- x
x = (3.60 x 10²⁴ x 24.31) / 1
x = 8.75 x 10 ²⁵ atoms
