How do you find the average relative atomic mass?
How do you find the average relative atomic mass?
To calculate the average atomic mass, multiply the fraction by the mass number for each isotope, then add them together. Whenever we do mass calculations involving elements or compounds (combinations of elements), we always use average atomic masses.
How do you find the mass of neon?
Actually Neon would be lested as having an atomic mass of about 20.18 because of a mixute of isotopes. Z= Atomic number the number of protons in the nucleus which defines the element. in this case Z=10 and this means neon but there is also 10 neurons in the nucleus of the major isotope whcich gives it ^20Ne.
What is the average atomic mass of neon 20?
Neon
| Isotope | Atomic mass (Da) | Isotopic abundance (amount fraction) |
|---|---|---|
| 20Ne | 19.992 440 18(1) | 0.9048(3) |
| 21Ne | 20.993 8467(3) | 0.0027(1) |
| 22Ne | 21.991 3851(1) | 0.0925(3) |

What does RNA look like?
Ribonucleic acid (RNA) is a molecule similar to DNA. Unlike DNA, RNA is single-stranded. An RNA strand has a backbone made of alternating sugar (ribose) and phosphate groups. Attached to each sugar is one of four bases–adenine (A), uracil (U), cytosine (C), or guanine (G).
Is protein heavier than DNA?
DNA having so long structure like of 200 nucleotides will be heavier than a protein with few amino acids. Similarly Protein having tertiary and quaternary structure are heavier than DNA, while secondary and primary may or may not be heavier than DNA.
Where is RNA located?
