The formula for an isotope of oxygen with nine neutrons, including the mass number and the atomic number is 17/8 O.
<h3>What is an isotope?</h3>
Isotope is any of two or more forms of an element where the atoms have the same number of protons, but a different number of neutrons within their nuclei.
This means that atoms of isotopes will have the same atomic number but a different mass number.
According to this question, an isotope of oxygen has 9 neutrons. If oxygen has an atomic number of 8, the formula of this particular isotope is as follows: 17/8 O.

Answer:
Coal is a traditionally used source of energy, there are main four types of ranks for coal. Here the rank of a coal means to a natural process called Coalification, which takes place during a plant is buried and changes to a harder, and denser material and become even more rich in carbon contents.
Anthracite is know to have the highest ranked coal, it contains highest percent of fixed carbon and lowest percent of volatile material.
Use dimensional analysis.
Now you try converting moles to grams. All you have to do is start with MOLES (Unlike the previous examples) over 1 then multiply that ratio by the ratio of molar mass over 1 mole. Hope this helps!
