Dimitry Mendeleef
Explanation:
Dimitry Mendeleef developed a table of elements which revealed regularities in elemental properties. He discovered the periodic arrangement of elements in 1869 while playing his game of solitaire.
- John Newlands in in 1863 proposed the idea of a repeating octaves of properties of elements.
- Dimitry Mendeleef described the periodic table or chart in 1869
- The chart was based on the periodic law which states that "chemical properties of elements are a periodic function of their atomic weights".
- In his periodic table, elements were arranged by atomic weights with recurring properties in a periodic manner>

Answer:
Explanation:
Hello,
In this case, given the temperature, volume and total pressure, we can compute the total moles by using the ideal gas equation:
Next, using the molar fraction of argon, we compute the moles of argon:
And the moles of methane:
Now, by using the molar masses of both argon and methane, we can compute the mass percent of argon:
