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.

The new volume of the hot air balloon is 801.9L.
As the temperature of the hot air balloon on the table is increased, the its volume also increases.
<h3>Charle's law</h3>
Charle's law states that the volume of an ideal gas is directly proportional to the absolute temperature provided pressure is kept at constant.
It is expressed as;
V₁/T₁ = V₂/T₂
Given the data in the question;
- Initial temperature T₁ = 26.7°C = 299.85K
- Final temperature T₂ = 48.3°C = 321.45K
To calculate the new volume we subtsitute our given values into the expression above.
V₁T₂ = V₂T₁
V₂ = V₁T₂ / T₁
V₂ = ( 748L × 321.45K ) / 299.85K
V₂ = 240444.6LK / 299.85K
V₂ = 801.9L

The first blank is splitting because water is made up of hydrogen and I think oxygen molecules. The second blank is I think fuel because there are cars that run on hydrogen.
The answer to this question should be Carbon dioxide.
To count the molar mass you need to add all the atoms weight that made up the compound. Carbon dioxide or CO2 is made of one carbon and two oxygen. Carbon molecular weight is 12. Oxygen molecular weight is 16. Then if you add them you will got: 12+ 2*16= 12 +32 = 44 g/mole.
