Answer:
35Cl = 75.9 %
37Cl = 24.1 %
Explanation:
Step 1: Data given
The relative atomic mass of Chlorine = 35.45 amu
Mass of the isotopes:
35Cl = 34.96885269 amu
37Cl = 36.96590258 amu
Step 2: Calculate percentage abundance
35.45 = x*34.96885269 + y*36.96590258
x+y = 1 x = 1-y
35.45 = (1-y)*34.96885269 + y*36.96590258
35.45 = 34.96885269 - 34.96885269y +36.96590258y
0.48114731 = 1,99704989y
y = 0.241 = 24.1 %
35Cl = 34.96885269 amu = 75.9 %
37Cl = 36.96590258 amu = 24.1 %

1) THE AGE OF THE SAMPLE 2) URANIUM- LEAD DATING
Explanation:
Answer is: an atom in a pure metal that's face-centered cubic has 12 neighbor atoms.
Fce-centered cubic has eight atoms at each corner of the cube and six atoms at each face of the cube.
Metals that possess face-centered cubic structure are copper (Cu), aluminum (Al), silver (Ag) and gold (Au).
There is three types of cubic cell:
1) simple cubic unit cell.
2) body-centered cubic unit cell.
3) face-centered cubic-unit cell.
