Answer is: silicon isotope with mass number 28 has highest relative abundance, this isotope is the most common of these three isotopes.
Ar₁(Si) = 28; the average atomic mass of isotope ²⁸Si.
Ar₂(Si) =29; the average atomic mass of isotope ²⁹Si.
Ar₃(Si) =30; the average atomic mass of isotope ³⁰Si.
Silicon (Si) is composed of three stable isotopes, ₂₈Si (92.23%), ₂₉Si (4.67%) and ₃₀Si (3.10%).
ω₁(Si) = 92.23%; mass percentage of isotope ²⁸Si.
ω₂(Si) = 4.67%; mass percentage of isotope ²⁹Si.
ω₃(Si) = 3.10%; mass percentage of isotope ³⁰Si.
Ar(Si) = 28.086 amu; average atomic mass of silicon.
Ar(Si) = Ar₁(Si) · ω₁(B) + Ar₂(Si) · ω₂(Si) + Ar₃(Si) · ω₃(Si).
28,086 = 28 · 0.9223 + 29 · 0.0467 + 30 · 0.031.
Answer:
E = 26.4 ×10⁻²⁷ j
Explanation:
Given data:
Energy of energy =?
Frequency = 4×10⁷ Hz
Solution:
Formula:
E = hf
E = hf
E = 6.6 ×10⁻³⁴ m²Kg/s . 4×10⁷ Hz
Hz = s⁻¹
j = m²Kg/s
²
E = 26.4 ×10⁻²⁷ j.
it must be a eukaryote because prokaryotic dna floats inside of it.
I am going toward selective breeding however it can also be genetic engineering.
