Answer:
The atomic weight of hypothetical element will be 63.568 amu.
Explanation:
Given data:
First isotope mass = 62.2 amu
Percentage abundance of first isotope = 24%
Mass of second isotope = 64 amu
Percentage abundance of second isotope = 100- 24 = 76%
Solution:
The atomic weight of hypothetical element will be the average atomic mass of its isotopes.
Average atomic mass = [mass of isotope× its abundance] + [mass of isotope× its abundance] +...[ ] / 100
Now we will put the values in formula.
Average atomic mass = [24 ×62.2] + [76× 64] / 100
Average atomic mass = 1492.8 + 4864 / 100
Average atomic mass = 6356.8/100
Average atomic mass = 63.568 amu

Answer:
24.3
Explanation:
I used a calculator and did 3x3x3=27 27x0.90=24.3
Answer: Mother has bb. Father has Bb.
Top left box= Bb
Top right box=bb
Bottom left box= Bb
Bottom Right box=bb
Why?
Mother has little b’s because the dominant trait would B would over power the b and give her browns eyes but she has blue so the answer is bb
Father has Bb because he has brown eyes and it says they are heterozygous meaning that he has a both the Dominant and recessive gene.
I hope this helped you :D
