Answer: The chemical formula of the gas is Xenon.
Explanation:
From Graham's law of effusion rates, the rate of effusion of a gas is inversely proportional to the square root of its molar mass.
Given: Rate of unknown gas = 
Putting the values in the formula:
Squaring both sides:
As Xenon (Xe) has molar mass of 131g/mol, Thus the chemical formula of the gas is Xenon.
Answer:
2. Isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behavior but with different atomic masses and physical properties. Every chemical element has one or more isotopes.
3. Since the vast majority of an atom's mass is found its protons and neutrons, subtracting the number of protons (i.e. the atomic number) from the atomic mass will give you the calculated number of neutrons in the atom. In our example, this is: 14 (atomic mass) – 6 (number of protons) = 8 (number of neutrons).

Answer:
If there is only one atom for the first element in the chemical formula, the prefix mono is typically omitted from the name. For example, CO is carbon monoxide, not mono carbon monoxide. ... Thus the chemical formula for carbon dioxide is CO2, not C1O2.
