The atomic mass can be defined as the mass of neutrons and protons in the atom. The atomic mass of the oxygen isotope is 18 amu.
<h3>What is an atom?</h3>
An atom is the smallest particle comprised of three subatomic units, namely electrons, protons, and neutrons.
The number of electrons in the atoms determines the atomic number, while the number of protons and neutrons determines the atomic mass.
The atomic mass can be given as:

The oxygen isotope has been comprised of 10 neutrons and 8 protons. The atomic mass of the isotope is given as:

The atomic mass of the oxygen isotope is 18 amu. Thus, option C is correct.

Answer:
A. All sites B. A site C. E site D. P site
Explanation:
A. Because all sites consequently take place while peptide is synthesized.
B. A site (aminoacyl site) is called so because it binds to charged aminoacyl peptide.
C. Because it is the exit site and it takes the final stage on the uncharged molecule.
D. The P site (peptidil site which takes main role in peptide synthesis.
1.6726219 × 10-27 kilograms
(The -27 is a exponent)
Ga₂O₃ + 2NaOH + 3H₂O = 2Na[Ga(OH)₄]
[Ga(OH)]⁻ + 3e⁻ = Ga + 4OH⁻
n(Ga)=It/(zF)
I=0.200 A
t=40.0 min=2400 s
z=3
F=96485.33 Kl/mol
n(Ga)=0.200*2400/(3*96485.33)=0.00166 =1.66*10⁻³ mol
The first one is the 2Hg+.....
The second is the Ca+ 2H2O....
The third is the first one, H2 + Cl2...
And the last is Fe+ S= FeS
It was so easy
Good Luck
